    "front-preface-001": "BEFORE WE START.",
    "front-preface-002": "Music advances. Ears notice its wonderful effects more. Yet minds seem less eager to dig into its true rules. Reason loses standing. Experience gains authority.",
    "front-preface-003": "Read surviving ancient writings. Reason alone helped those writers find most properties of music. Experience still supports most of their rules. Yet today we favor practice alone. We neglect what reason could give us.",
    "front-preface-004": "Experience shows what music does. Alone, it cannot reveal music's basic principle with the precision reason needs. Its conclusions often go wrong. Or doubt remains. Reason must clear that doubt. Example: we say our music is more perfect than ancient music. How prove it? Ancient writers claimed effects our music no longer seems able to produce. Maybe familiar things surprise us less. First we marvel. We get used to them. Marvel fades into amusement. But this proves equality at most. Not superiority. Try another path. Suppose one clear principle lets us draw sound, certain conclusions. Suppose these show our music has reached its highest possible perfection, while the ancients fell far short. See Book II, Chapter XXI. Then we know where we stand. We also better understand that point about familiarity. We know the art's limits. We pursue it more willingly. People with great musical taste and ability need not fear missing the knowledge needed for success. Experience can keep raising doubts. Reason clears them. That gives firm grounds to expect success in this art.",
    "front-preface-006": "Modern musicians means musicians since Zarlino.* They should copy the ancients here: explain why their practice works. Then many prejudices against them could end. Their own stubborn prejudices could end too. Experience serves them too well. It tempts them. Each day it shows new musical beauty. They rarely study that beauty's causes deeply. Their knowledge works for themselves alone. They cannot pass it on. They miss this fault. Others fail to understand; they act surprised. They rarely ask why they cannot explain themselves. Harsh charge. I admit it. I may still deserve it myself, despite all my efforts to avoid it.",
    "front-preface-007": "Still, I hope this criticism moves them as it moved me. I risk publishing my new findings chiefly to revive that old, noble drive to match and surpass good work. Music has natural simplicity. I try to reveal it. Mind should grasp its properties as easily as ear hears them.",
    "front-preface-008": "* Zarlino: famous music writer. Wrote about 150 years before this book. Later books on the same subject give only weak copies of his work.",
    "front-preface-010": "One person cannot finish exploring so deep a subject. Even with great care, something almost always gets missed. Still, new discoveries add to earlier work. Each opens a path. Others can go farther.",
    "front-preface-011": "Music is a science. It needs certain rules. Rules need one clear foundation. We can scarcely find that foundation without mathematics. I practiced music for many years. I gained experience. Still, only mathematics cleared my ideas. Before that, confusion remained. I had not even noticed it. I could not tell principle from rule. Then the principle became simple and clear. Its consequences gave me rules. Every rule had to connect back to that principle. Now I understood their meaning. Their correct use. Their connections. Their order. Start with simpler rules. Move gradually to harder ones. Even choosing terms became clear. I had not understood these things before. Someone once spoke while I praised modern music's perfection. They wished our century's musicians knew as much as the beauty of their compositions deserved. Now I had to agree. Feeling an art's effects is not enough. Same for science. Understand those effects well enough to explain them. That is my chief aim here. Four books.",
    "front-preface-012": "FIRST BOOK: a short account of relationships between sounds, consonances, dissonances and chords. Find harmony's foundation in one sound. Explain its chief properties. First division produces another sound: its octave. They seem like one. The original sound then uses that octave to form every chord. Chords contain only the fundamental sound and its third, fifth and seventh. The octave creates all their possible variety. Other properties appear too. Less directly useful for practice, yes. Still needed to lead us there. Demonstrations stay fairly simple.",
    "front-preface-013": "SECOND BOOK: theory and practice, equally. The principle becomes a musical part: the fundamental bass. Explain all its properties. Explain intervals, chords and modes too; they depend entirely on it. Also discuss how to make music perfect in performance. Use the first book's reasoning when useful. Use experience. Use the best musical writers. But criticize their mistakes. New ideas must reach different readers. Scholars: give reasons. People who trust only ears: give experience. People who trust teachers' rules too much: expose errors those rules may hold. Help readers accept the rules freely. Later books set them out in order and greater detail.",
    "front-preface-014": "THIRD BOOK: a special method. Learn composition very quickly. Method already tested. But people rarely believe this without trying for themselves. So I will not insist. If method is new to you, see what it produces before attacking it. Person who wants to learn cares little how teaching works, provided learning succeeds.",
    "front-preface-016": "No rules yet teach composition at today's full level of perfection. Skilled composers admit it: experience alone supplied almost all their knowledge. They try to teach others. Often must add this musicians' proverb: Cætera docebit usus. Practice will teach the rest. Yes, some excellence needs talent and taste. Experience can help these more than knowledge itself. Still need thorough understanding as a guide. Otherwise experience may deceive. At least, understanding connects new ideas from experience to their true foundation. It also puts talent and taste to work. Without understanding, those talents often go unused. So I sought a faster, easier path to this perfection. Until now, people reached it through practice alone. Start with a reasoned, precise, clear grasp of all harmony. Explain just three intervals. They form two main chords. They also form the whole progression of fundamental bass. That bass determines the other parts' progression too. Everything else rests on this understanding. First reading of this book can give it. Readers can readily check.",
    "front-preface-017": "FOURTH BOOK: accompaniment for harpsichord and organ. Hand position. Finger arrangement. Everything that helps build practical skill as quickly as possible.",
    "front-preface-019": "Other instruments accompany much like harpsichord. These basic rules work for them too.",
    "front-preface-020": "Last two books closely connected. Both help practical composers. Both help accompanists. Want nothing left unexplained? Consult second book too—assuming I forgot nothing. Others can surely improve on my work. I tried to miss nothing. My long discussions and repetitions prove the effort. This fault has two causes: I want clarity, and my ability is limited. First book is, in one sense, unnecessary for practice. Use it as you judge best. I put it first only to prove this treatise's claims about harmony.",
    "front-preface-021": "My job kept me from supervising printing. So I reread the work with fresh care. Found changes and necessary corrections. They appear in the supplement at the end. Two tables stand at the beginning. One lists subjects. One explains terms readers need. Together they introduce the whole work. I dedicate it to the public.",

Take viol with strings long enough to see vibrations. Sound one string strongly. Strings octave below or above vibrate by themselves. With fifth, only higher sound vibrates, not lower.

More: inversion only moves sound to octave, or number to double. Relation changes only by difference of proportion. Ear scarcely notices that difference. 2 to 4 gives nearly same effect as 2 to 2. Reasoning and experience prove enough. Hence octave receives same force as its principal, fundamental sound. Zarlino says:* octave is mother, source, origin of all intervals; dividing its two terms generates all harmonious chords. True in one sense. Yet division of single fundamental sound generates every other sound, hence every interval and chord. To uphold Zarlino, add this: fundamental uses octave as second term. All intervals generated by division must answer to it. Thus fundamental more clearly their beginning and end. Octave has only properties received from fundamental that generates it. More exactly: same sound moves into octave or replica—or multiplies, if you prefer. This determines intervals in every direction for each generated sound. Properties from first comparison with fundamental remain unchanged. Perfect consonance with fundamental remains perfect with octave. Imperfect consonance or dissonance on one side remains same on other. Sound required to rise or fall on one side rises and falls on other. What agrees on one side agrees on other. Nothing changes, except this: principal-consonance chords have perfection when fundamental occupies natural lowest position. Move fundamental to octave: that perfection changes. Same consonances take different order, introducing variety. Test earlier diagram. Full arrangement gives very great satisfaction. Remove sounds 1, 2; then remove 1, 2, 3, 4.

He says no sound is heard without upper octave also seeming to strike ears somehow. Perhaps he would add lower octave, had his lute proof not misled him, as said earlier. Or had he accepted Aristotle’s view. Desermes* reports Aristotle’s Problems 24 and 43: pluck nete, upper octave string; hypate, lower string, also sounds. High sound’s fading end becomes low sound’s beginning, like echo or image of high sound. Almost every musician says certain sound, note, or interval “is implied,” sometimes “in the bass.” Expression often comes before user understands its force. Harmonic ratios give only perfect chord. Admit derived sixth and sixth–fourth chords only by supposing perfect chord’s fundamental implied in its octave. Otherwise destroy every principle. Further evidence: third-and-fifth chord remains perfect and complete without octave. Octave generated first; therefore seems implied. Put octave above third and fifth. It now forms sixth and fourth with them. Chord remains good, though fundamental absent. Thus fundamental transposed or implied in octave. This makes latter chord less perfect than first, despite same sounds. “Principle inverted,” “identified with octave,” “transposed into octave,” “implied in octave”: same meaning. Upper octave sound is no different principle. It represents immediate generating principle and forms one whole with it. Every sound, interval, chord must begin and end there.

    "I.03-040": "Pay close attention to inverted comparison from previous article. Key to all harmony’s variety. Know it; greatest difficulties can be overcome. Needed knowledge: intervals made by comparing middle number with each octave endpoint. Take 3, arithmetic mean of 2 and 4. With 2: fifth. With 4: fourth. Difference: interval from low, fundamental octave sound must be more perfect than interval from high sound. Further proportional difference need not detain us. It comes only from octave versus unison—as if comparing 3 with 2, then again with 2. No difference there. Octave’s two sounds scarcely differ from unison; seem one. Thus 2, 4 gives nearly same effect as 2, 2. Likewise, two intervals differing only through endpoint 2 or 4 should count as almost equal. Prefer interval where fundamental keeps natural position: it comes directly from fundamental. Hence use arithmetic proportion. Simple operation: find mean of two numbers, like 3 between 2 and 4. Those following multiplication invented harmonic proportion. It merely reverses arithmetic proportion; next chapter explains. Each proportion applied to its proper object gives fifth from octave’s low sound, fourth from high sound. Apply either to other’s object: fourth on low side, fifth on high side. Deeper study reveals inversion everywhere. Examples: numbers naturally increase; harmonic progression must decrease. Arithmetic proportion works on one side; harmonic proportion gives same effect on other. First proportion requires numbers to mark divisions of unity. Second requires reversed numerical order. Natural numerical progression, with numbers marking unity’s divisions, requires dividing given string. Reversed progression requires multiplying string. Division yields higher sounds, as it should. Multiplication yields lower sounds, against natural order; harmonic proportion remedies this. Finally, octave has close relation already described. Deny it, and overthrow reason and experience. Divide octave: fifth comes first in its kind, defined against low, fundamental sound. Fourth follows as fifth’s “shadow”—Descartes’s word.* It comes from reversing the two sounds that first made fifth: transpose octave’s low sound to high sound. This last inversion is principal subject of this work.",

    "I.03-047": "Further proof: hear pleasing effect of all consonances in earlier diagram’s order. Consider each property. Octave so united with generating principle that they become inseparable. Hence no further mention needed: octave implied. Fundamental takes fifth to form all chords, then joins third to determine their construction. Fifth contains major and minor thirds. Both thirds cannot relate to principle at same time. Yet if one arises directly, other must receive same privilege. Major–minor difference changes no interval kind: both remain thirds. Fifth cannot bound intervals; only octave can. Everything between principle and fifth depends on octave, inseparable from principle as already proved. Judging interval by another requires octave’s help. Thus set fifth and major third aside to judge minor third. Imply octave of minor third’s low, fundamental sound. Give it same privileges as octave in origin of every interval. Fifth 2–3 comes directly from fundamental of octave 2–4. Invert: fourth 3–4. Same operation: transpose fundamental 2 to octave 4. Major third 4–5 comes directly from fundamental of octave 4–8. Invert: minor sixth 5–8. Minor third 5–6 comes directly from fundamental of octave 5–10. Invert: major sixth 6–10, or 3–5. No difference in direct origin of fifth and both thirds. No difference in indirect origin of fourth and both sixths. Possible objection: minor third’s principle differs, since 5 is not multiple of 2, taking 2 as unity here.

Thus Descartes’s conclusions false, except about sixths’ properties. He confuses properties with origin. Shared third-and-sixth properties belong only to major or minor kind; every third and sixth belongs to one of these.

    "I.04-003": "Descartes proposes equal string division to prove consonances’ origin. We have not set this account out here. Proof requires reversing natural numerical progression. Numbers then mark multiplication of resulting string lengths. Harmony’s whole order disturbed: octave naturally needs fifth below, but gets fourth below instead. Followers of reversed progression invented harmonic proportion to restore natural chord form. Know its nature, and you must admit it reproduces arithmetic proportion point for point. Reverse number order; must also reverse proportion to recover every perfection of natural order. When objects differ only by inversion, two proportions’ uniformity is obvious. No more discussion needed. Most arithmeticians and geometers unfamiliar with music merely cite harmonic proportion, without defining properties. Apparently they knew none. Reverend Father Pardie says:* discussion of this progression or proportion so far is of little use; he will not undertake extraordinary claims here. * Desermes discusses subject fully. Air movements producing consonances and dividing octave into fifth below, fourth above follow arithmetic proportion, not harmonic: numbers 2, 3, 4 show it. Later he says so-called harmonic proportion should be called arithmetic proportion or progression. Perhaps Greeks therefore ignored former. Leave that question aside. Did Zarlino have good reason to dwell on it? Focus on him: model for later authors; usual authority for practice; still oracle to some musicians. Monsieur de Brossard even calls him prince of modern musicians.",
    "I.04-005": "* Zarlino first admits: music subordinate to arithmetic; unity, principle of numbers, represents sounding body used to prove sound relations; unison is principle of consonances. Then demonstrations and rules forget all three. Deeper he goes, further he leaves declared principle. Whole string proposed for division still reveals sounding body. But he erases it from thought by separately comparing resulting lengths. Whole string becomes just another length, dependent on parts that previously depended on it. As if building instruments were main task, he demands measurement of lengths already fixed by numbers defining equal divisions. Those numerical relations alone give fullest desired knowledge of harmony. For proof, attach new idea to numbers. Music subordinate to arithmetic; harmonic progression decreases while arithmetic progression increases. Thus numbers multiply unity in arithmetic, but divide unity in harmony into as many equal parts as they contain units. Study number properties only: music appears simple and natural. Proof equally easy by either method. Zarlino refuses to risk this supposition. Instead, second operation wearies mind, reversing natural number order and beautiful harmonic order first revealed by string division. Test proves it. Test also shows him falling into fault he meant to avoid. Each length uses common measure. Apply measure as many times as number contains units; string grows accordingly. Numbers therefore multiply given string, sounding body represented by unity; they do not divide it. Granted: largest number can mark whole string, smaller numbers its divisions. But largest number cannot remain principle everywhere. More or fewer string divisions change its quantity. More divisions push principle further away, finally out of sight. Take 6, 5, 4, 3, 2, 1. Call 6 principle; hear all sounds from specified lengths. Error becomes clear immediately. Remove 6, call 5 principle: same. Remove 5, use 4: same, and so on. This order has as many imperfections as opposite order has perfections, under properties assigned to each. Repair second operation with third: Zarlino multiplies numbers by method explained in Chapter XI. He or others call resulting progression harmonic proportion. It only recovers what arithmetic proportion gave in first divisions. But former clarity becomes obscurity. Original root numbers and lengths disappear from consideration. Start new operations, as if previous findings useless. New operations merely recover lost path. Yet wandering too far has hidden principle; hard to recognize now. * Reverend Father Mersenne makes this clear. Harmonic number is number of air movements caused by string vibrations.

Likewise bass fails, whole musical piece fills with dissonance and confusion. Compose bass with somewhat slow, separated movements, wider than other parts' movements. Then other parts can move by adjacent steps, especially soprano: this is its property. Yet compare clear, sound definition with author's rules and examples. Contradictions everywhere; doubt and uncertainty persist.",

First string divisions give consonances forming perfect harmony together. Part representing whole string can progress only by these consonant intervals. Each sound agrees with preceding sound. Each can carry chord like first divisions' chord, representing whole string as chord's principle and foundation. This explains Zarlino's separated bass intervals. Consonant intervals must be separated. His slow movement means slow relative to other parts. Those must move diatonically; upper parts can make several steps between consonances while bass makes one. For initial rules, however, all parts move equally to keep matters simple and clear. Do not confuse octave with prescribed bass progression. Fundamental may stand several octaves higher or lower, provided always beneath other parts. Fifth suits bass best. Every final cadence or melodic conclusion makes this progression primary. Anyone sensitive to harmony feels compelled to move bass this way at any melodic conclusion. Same holds for fourth, which represents fifth. Low enough voices naturally descend fifth; others ascend fourth. Clear proof of octave's power: either constituent sound represents it. Also proves relation of fourth and fifth from octave's division. Prefer fifth whenever voice permits. Substituting fourth does not destroy fifth. For pleasant suspense, bass can move by one or several thirds: fifth consists of two thirds. Thus can use representative sixths too. Reserve all cadences for fifth and representative fourth. Fundamental bass progression confined to these consonances. Dissonance sometimes forces ascent of whole tone or semitone. License comes from interrupted cadence, discussed later. Ascending tone or semitone—not descending—is inversion of seventh then sounding between its two sounds.

Natural to distinguish preceding sound by making it less perfect. Both carry perfect chords? Soul desires nothing more after either; uncertain which sound to choose for repose. Dissonance needed: harshness makes following repose more eagerly desired. Nature's involvement shows in necessary choice of third. Only consonance compensating dissonance's harshness.

Major third naturally lively, cheerful: all major or augmented shares this. Minor third naturally tender, sad: all minor or diminished shares this. Zarlino* says thirds' outer sounds naturally move toward what approaches their being. Major wishes to become major: rises. Minor descends. Clear to skillful, discerning musicians, since upper part moves semitone. Semitone is salt, so to speak, ornament and cause of beautiful harmony and good modulation. Without it, modulation almost unbearable. These two progressions give all major, augmented, minor, diminished intervals' progressions. General rule: major or augmented rises; minor or diminished descends.",

Minor and diminished may also descend whole tone, according to modulation. Extraordinary: he praises semitone, then abandons it where strongest. Perfect system places semitone between octave and sound preceding it in ascent. Octave determines repose; diatonic ascent reaches it only through semitone. Preceding sound therefore matters as much as octave: pass through one to reach other. Zarlino says major third and major sixth must rise to octave—rule from this observation. Yet forgets tritone shares rule. Mentions it only briefly; omits from perfect cadence. Other major or augmented dissonances from this major third, formed with octave's preceding sound, receive even less attention. Least discussion of what follows his semitone rule without restriction.

Countless melodies and chord successions appear at every step. Compose piece freely; inversion's variety continually awakens listener. Writers feeling inversion's effects did not trace origin. Rules and examples prove it. Different chord, different example, different rule. One says seventh resolves by third, fifth, octave, sixth. Another says diminished fifth resolves by third, fourth, tritone, ninth—descending, ascending, or holding still. Thus sciences made obscure: separate treatment of each part instead of simple intelligible whole. Seventh dissonance appears as diminished fifth, second, ninth, eleventh; resolves through different intervals. Cause only different bass progression.

Both from fundamental bass beneath fundamental chords. Rest depends on taste. Any chord sound may serve as bass. Sound shared by consonant chord and following dissonant chord, whose dissonance cannot prepare, must syncopate or stay on degree—nearly same thing. Still clearer if chord unchanged and its sounds pass successively above held or syncopated bass. Separate rule unnecessary: free choice. Yet rule arose from these varied properties glimpsed through experience. Writers preserve demand that every dissonance syncopate, then nearly destroy it by allowing bass syncopation under fourth, seventh, and so on. First rule makes syncopated bass dissonant; fourth and seventh then not dissonant. Writers deny yet imply this. Why separate bass rule?

Unrestricted with consonant chords; not so with dissonant chords, though new dissonant interval expands its resources. Added dissonance depends on perfect chord, cannot exist without it. Perfect chord depends on lowest sound, foundation of both chord and dissonance. In most natural harmony, bass moves toward that low sound when sounding and resolving dissonance, seeking support against harshness. If dissonance obscures principle, bass searches more attentively: descends third or fifth. Even then, only fifth gives pleasant resolution. Fifth first harmonic interval; octave merely repetition. Bass descending seventh or rising second begins license, even if consonance prepares and resolves dissonance. This supports claim: descending seventh still approaches principle. But seventh owes origin more to taste than nature; unlike perfect-chord intervals, it is absent from harmonic body’s most natural operations. License comes from it alone. Those crediting taste more excusable than those rejecting licenses beyond their understanding without reason or experience. Descending seventh/rising second forms interrupted cadence. Ear expects desired perfect conclusion, then meets interruption and surprise, somewhat offended. Surprise means departure from natural course; departure means license. If descending third, fifth, even seventh naturally sound prepared/resolved dissonance, their inversions allowing unprepared dissonance also count as license. So does any departure through supposition, borrowing fundamental sound, or alteration of either fundamental chord. Yet restricting harmony to most natural alone gives it too narrow bounds. Refusing its full properties denies its rights. Refusing what its principle offers abandons senses and reason.

Addition follows naturally by rule of three or fresh multiplication of original chord’s numbers, Book I, chapter VII, page 29. Musical rules concern usable consonances/dissonances.

Universal demand for preparation/resolution considers only first descending fundamental movements: third, fifth, seventh. Only these allow both; fifth primary.

Student progresses; then adds another part, and ideas vanish. Melody no longer under control. Seeking one part's path relative to another, we lose original plan or must change it. Keep first part unchanged, and its constraints may deny other parts their best melodies. Harmony guides us, not melody. Skilled musician can plan beautiful melody suited to harmony. Whence ability? Nature may help, certainly. If nature denies gift, only rules bring success. Where do rules come from? Must examine.",

Second and third divisions generate all harmony, but their sounds no better suited to melody alone. Only thirds, fourths, fifths, sixths, octaves still make imperfect melody. Harmony generated first. Melody's rules must come from it. Take harmonic intervals separately; form fundamental progression—not yet melody. Put intervals together above one constituent sound. They naturally follow diatonic path fixed by their progression while serving each other as foundations. Consonant and diatonic progressions yield all needed melody. Harmonic intervals had to be known before melodic ones. Beginner's teaching consists of these consonant intervals, if such thing counts as melody. Chapter XXII shows ancients also derived modulation only from melody, though modulation comes from harmony.",
    "II.19-006": "Know consonant progression: adding three sounds above bass no harder than adding one. Two instructions: 'Put third, fifth, OR octave above bass'; 'Put third, fifth, AND octave above bass.' Both require same interval knowledge. Known intervals no harder together than separately. Part making third must next make fifth when bass descends third; this is our explanation. Bass moves differently; third here, octave there, fifth elsewhere. Must know what follows each under each bass movement. Thus teach four-part composition unknowingly while explaining only two parts. Each consonance appears in turn; must know each one's succession. Using all together no harder than individually. Cannot distinguish all at once? Attend to each separately. Move from one to next; construct perfect four-part harmony. Draw all further knowledge needed for perfection from it. Added explanation prevents error, if we trust experience of several people: knowing only note values, they read rules twice and composed harmony as perfect as desired. Composer hearing own work* also trains ear gradually. Become sensitive to perfect harmony taught by these beginnings; success assured. Success depends entirely on first principles.",

Such mastery almost impossible: no foundation guides it. Teaching stays barren. Memory insufficient; method scarcely encompasses everything. Teacher finally says: Cætera docebit usus—practice teaches rest. Move to three or four parts? Explanations so scant, need great masters' own genius and developed taste to understand them. Zarlin* says four parts scarcely teachable on paper. Leaves composers to discretion, trained by earlier two- and three-part rules. Our view opposite. Teach harmony in four parts: all its distinctive features occur in only two chords, as shown throughout. Easy then to reduce to three or two. Zarlin fully defines neither two nor three; admits inability to define four. Yet concedes perfect harmony consists of four parts, likened to four elements. (Chapter 58, folio 281.

Principal notes from C’s perfect chord: third mediant, fifth dominant. Sixth chord found better on mediant than fifth chord; unexplained reason: inversion of tonic’s perfect chord, thus mediant represents tonic. Dominant likewise takes perfect chord with major third. Seventh containing diminished fifth assigned only to dominant immediately before tonic. These two make perfect cadence. But authors omitted that diminished-fifth/tritone chords derive from seventh chord. Seventh precedes tonic perfect chord; derivatives must precede same or its derivatives. Experience knows; rules silent. Principle would clarify: such seventh or derivative demands tonic perfect chord or derivative next. Two chords contain every mode note except sixth, easily found by third’s nature. Also give chords before tonic/mediant. Need chords before dominant. Perfect chord preceded by seventh a fifth above; dominant normally perfect, added seventh leaves foundation intact. Thus dominant too preceded by seventh a fifth above. New chord’s third must be minor to preserve mode—same note as tonic dominant’s seventh or tonic’s fourth. New seventh chord contains mode’s sixth. Thus know octave intervals and their chords, derived by inversion from fundamentals. Minor differs only in minor third/sixth, with sixth qualifications in next book.",

Each note made principal supposedly gave different effect. Forgot model. Perfect system not worth imitation? They flattened B for fourth above F, copying consonances, yet ignored tonic approaches. C–D tone; C–B semitone. E tonic retained E–F semitone and D–E tone instead of sharpening F/D to match model, as B had been flattened. “These differences distinguish modes”? Experience proves error. Zarlin’s reflections contradict rules. Bass, he says,* foundation of all parts;* natural perfect cadence falls fifth. Examples include rising semitone to final; others also descending tone. Gather approaching notes: rising one dominant’s major third, falling one dominant’s fifth. Perfect ending: dominant then tonic. Dominant perfect chord contains major third/fifth. Thus tone from fifth to tonic, semitone from major third to tonic. Every mode needs these. Bass falling fifth cannot give perfect cadence unless upper parts rise semitone and fall tone. Piece must end perfect cadence on principal note, or soul unsatisfied. Absurd to propose modes incapable of this. Zarlin’s ban on minor third/sixth rising to octave follows same principle. Dominant needs major third, semitone below tonic octave, like B–C. Ancient D/E/G/A modes lack semitone. Melody alone guided them; harmony would prevent gross errors. Zarlin abler, but too deferential to Church plainchant, long established, hard to reform through custom/cost. Only keys matching perfect system suit harmony. Tasteless people steeped in misunderstood ancient rules vainly seek pleasing harmony on such chants. Yet this should occupy study and labor: music made only to praise God. Believer distressed, unable to unfold genius on great subject. Can pile correct chords to end; faultless music differs greatly from perfect music. Ancients enslaved to discoveries made melodies first, then harmonic rules from them. Should start with harmony—string division proves priority—then derive melody.

But mode can change major to minor, or minor to major, with tonic unchanged. Example: cheerful subject becomes sad, or sad becomes cheerful. Most chaconnes and passacaglias do this; often two successive airs of same kind do too. Then mode changes, key does not. C remains tonic in major and minor alike. To avoid confused terms, say major key or minor key. Regarding melodic and harmonic movement, key changes only major to minor or minor to major. Regarding tonic, key can start on twenty-four different notes of chromatic system—but not freely anywhere within piece. Any chosen note may begin and end piece.

So-called major/minor sevenths differ by this semitone; same with fifth/diminished fifth. Yet nobody calls diminished fifth minor fifth, augmented fifth major fifth. Major/minor properly belongs to thirds and direct dependents: inverted sixths, modes governed by thirds. Altered fifth/fourth called augmented/diminished, signaling improper proportion.

Seventh always descends unless augmented. So-called major seventh equals our augmented interval: choose. Both ratio 8:15. Augmented rises like major third forming it—tonic dominant’s major third in fundamental harmony. So-called major descends like minor third.

Book I explained: these intervals replace naturally expected ones, tolerated for modulation. Still never called minor fifth or major fourth.

Therefore major dissonances need none either: Book Two, Chapter XIII. Seventh must be prepared by a consonance. All minor dissonances must too. Stay in key being treated: a note consonant in previous chord may now form dissonance. Same possible between keys, once their connection can be made pleasing. Remember: one note can serve successive dissonances when their chords are fundamentally the same chord. Also, seventh or diminished fifth can prepare eleventh, though both are dissonances. Thus a note already dissonant can form another dissonance in a chord that seems different in some respect. Condition: no change of key in that case.",
    "III.18-004": "We said: seventh prepared only by third, fifth, octave. This concerns fundamental bass progression. Most natural bass movements: down third, fifth, seventh. Up second equals down seventh; other related intervals work likewise. Usually choose smaller related interval for bass. Prefer up second to down seventh; same principle elsewhere. Now consider inversion. Any note of fundamental chord can occupy bass. Chord name changes with intervals its sounds form above that bass note. Here, sixth or fourth prepares seventh instead of third or fifth. Elsewhere, third, fourth, fifth, sixth, even octave prepares diminished fifth. Diminished-fifth chord represents seventh chord, as does every other dissonant chord. Any consonance can therefore prepare dissonance without error, unless we deliberately avoid natural movement. Example: replace bass tonic with its mediant or dominant, each carrying chord derived from tonic's perfect chord. Want seventh prepared by tonic's octave, fifth, or third? Octave becomes sixth above mediant, fourth above dominant. Fifth and third change correspondingly. Thus first rule for sevenths applies to all minor dissonances. Likewise, after tonic's perfect chord—bass tonic, mediant, or dominant—we may sound diminished fifth, tritone, great-sixth or small-sixth chord, and so on, instead of seventh that a consonance of perfect chord must prepare. Reason: another note of seventh chord now replaces its fundamental note in bass.",

Conclusions always fall on measure’s first beat. Even slightly trained taste hears them at once. First-beat notes where melody rests must always bear perfect chord. Therefore treat them as tonics.",
    "III.25-005": "2. After tonic, bass moving by consonant intervals may bear perfect chords up to note followed by diatonic interval. Exception: note third above or below another bearing perfect chord may take sixth chord; this is even preferable. Conversely, first note requiring perfect chord makes next note third above or below take sixth chord—unless another consonant progression follows that second note. Consonant progression naturally requires perfect or seventh chord on each note. More explanation follows.",

    "III.25-011": "B. Note third above dominant, equivalently sixth below, could bear sixth chord. Diminished-fifth chord fits better: note is leading note of C. Key of C continues through C. Add diminished fifth to sixth chord: diminished-fifth chord. Add seventh to perfect chord: seventh chord. Could have added seventh to dominant immediately preceding diminished-fifth chord. See Chapter XI.",
    "III.25-012": "Four notes rise in successive thirds from tonic. Mediant bears sixth chord; dominant bears sixth–fourth at C, not perfect chord. Flat on B determines new key. Bass reveals it through diminished fifth between B-flat and following E. E, lower sound, becomes leading note. B-flat chord must fit key prepared by that leading note. B-flat lies outside C, key being left. C’s dominant also adapts chord to following harmony. Still within C, it bears sixth–fourth making up B-flat’s tritone chord. Perfect chord on this dominant would require minor third to avoid false relation. False relation: successive notes in different parts share name, but added sharp or flat changes one. Example: B sounding as G’s major third in one part forbids B-sharp or B-flat next in another. More later. Sixth–fourth at C therefore brings harmony closer to next chord. Perfect chord with minor third also possible. Small-sixth chord possible too, with diminished-fifth chord on immediately preceding note: E and following B-flat form diminished fifth. Such bass interval determines key absolutely. Its lower sound always leading note, as stated. Tritone likewise determines key; upper sound is leading note. Exception: after interval, bass rising fourth or falling fifth may remove this leading-note role. Each note can act as dominant seeking tonic dominant. Tonic dominant immediately follows notes forming diminished fifth or tritone: G, H, J. This applies only between second and sixth notes of minor keys, forming diminished fifth or sharp fourth.",

Add G-sharp: F-sharp loses leading role; G-sharp becomes leading note, indicates A key. Count in sharp order F, C, G, D, A, etc.; no mistake possible. Ignore flats mixed among sharps. Without sharps, flat marks new key. Leading note is note that would take next added flat. Example: B-flat, no sharp; next flat would be E-flat, so E is leading note. With E-flat, A is leading note. Follow flat order B, E, A, D, etc. Next unflattened note after flattened note is leading note. Recall Article One: bass diminished fifth or tritone also reveals leading note. Note eligible for next flat lies tritone above or diminished fifth below last flattened note. Never use natural sign here; avoid confusion.",
    "III.25-033": "2. Bass need not reach leading note. Key can change without this clue. Bass often forms diminished fifth or tritone between minor key’s second and sixth notes—rather, sixth to second. This applies without sharp; sharp always decides. First check suggested key’s proper relation to departing key. Then check note after repose partly established by diatonic progression: does it favor one key?

G becomes natural at B: no longer leading note. No sharp or flat before C cadence. Thus C key declared from A onward.

Exception at M: rising fourth requires seventh chord on C, perfect chord on F, since consonant interval follows F. Perfect chord always makes its bass tonic; thus F becomes tonic again. But F’s required B-flat disappears instantly. No sharp or flat remains; B becomes leading note again. C interrupted briefly for variety, consonant bass progression permitting it.",
    "III.25-048": "Concluding rule: consonant progressions decide absolutely. Fit diatonic passages to following consonant motion rather than preceding motion. Leading note unclear? Keep chord sequence prescribed in Chapter XI’s octave, starting from last consonant chord borne by last note in consonant progression. Bass rising semitone may suggest first note is leading note. Check for following sharps or notes losing flats: stronger evidence. Rising semitone also occurs from mediant to fourth in major, second to mediant in minor, or dominant to sixth in minor. In last case, sixth immediately descends. Consonant progression, sharp, flat, or particular chord sequence must decide.",

Major/minor distinction comes from third and fifth, formed from old key’s notes. Leading note almost certainly appears before or after; following consonant progression almost certainly reaches determining conclusion.

Measure five: sixth against upper, seventh against fundamental. Measure six: ninth. Follow fundamental motion again only at final conclusion. Continuo/fundamental intervals reveal chords.

Sixth–fourth chord on dominant stands for perfect chord that tonic should naturally have carried after dominant seventh. Dominant can also move to mediant. Basic harmony of those two chords stays unchanged. Chapter VIII gives another rule: rise by step after seventh chord, to perfect chord or another seventh chord. This comes from interrupted cadence.

Sometimes remove particular dissonances too.",

Repeat in middle of word or phrase: meaning may become hard to hear. Organ does not need this. Sounds stay “contained”. [Printed error. Supplement says “continuous”.]",
    "IV.18-006": "4°. Keep chords in keyboard's middle, as far as bass allows. Need another register: shift on same chord if possible. Otherwise shift after consonant chord. Never after dissonant chord. Cannot always control this: composer may send bass two octaves up or down unexpectedly. To shift, find a key shared by current and next chord. Look or feel for it. Moving up: put lowest finger on that key. Moving down: put highest finger there. Do not lift whole hand. One finger takes another's place and makes the shift. Eyes can stay on score.

Often major sixth needs figure because new transposed modulation requires sharps absent from signature. Not necessarily chord meant here. Small sixth itself often minor.
