The six-four chord
Taught in 6 books. Each one opens at the passage; ▶ plays the example beside it. Also called six-four chord, cadential six-four, second inversion, 64 chord.
This index is Playable Books’ own: a first pass that finds the term’s words in each book, corrected by hand. The authors did not tag these passages, and their terms can differ (Fux’s “ligature” is a suspension). The quoted text is the book’s.

- Chapter XVI. Three-Part Harmony
The second inversion of any triad-form (the 6/4 chord) is rare and hazardous. It would be wise for the student to avoid all 6/4 chords, excepting the second inversion of the I, and of the IV. These are good.

excepting, as usual, during chord-repetition. Six-four chords should not occur in direct succession. For illustration, this lower part is faulty:

In the six-four chord-form, the bass tone (the chord-5th) is generally doubled.

§ 2. Every triad has two inversions: the chord of the sixth (first inversion), figured 6, and the chord of the fourth and sixth (second inversion), figured 6/4.

A chord of the fourth and sixth is one whose bass is the fifth of the root.

…of the sixth [E–G–C] is the chord of the sixth on the first degree, and the chord of the fourth and sixth [D–G–B] is the chord of the fourth and sixth on the fifth degree, and so on.

The second inversion, or chord of the fourth and sixth, is made of a fourth and a sixth above the bass. For example, the chord of the fourth and sixth [G–C–E] consists of a fourth [G–C] and a sixth [G–E]; it can also be seen as a fourth and a third [G–C, C–E].

§ 22. — 1) By the cadence formula of the second kind is meant the succession of the chord of the fourth degree, the six-four chord of the first degree, and the triads of the fifth and first degrees.

2) The cadential six-four chord is connected harmonically with the triad that precedes it; thus the fourth of the six-four chord is a common note.

In the chord of the sixth the third appears doubled; in the chord of the six-four—the fifth. A doubling of the third, however, being unnatural and unsatisfactory to the musical ear, it is better to double the fundamental tone or the fifth in the chord of the…

…not at all unpleasant; so that the close position of the upper voices of the six-four chord may be retained. The fundamental is doubled only in cases where we wish to avoid concealed octaves, which sound especially bad in the six-four chord.

- a) THE SIXTH CHORD
In the six-four chord, then, the arrangement of the chord tones resembles the overtones of the bass note more closely than in the sixth chord. The inherent sound of the six-four chord’s bass note finds less resistance to its will in the chord tones; or, as one…
▶ Fig. 24 nearby - b) The Six-Four Chord
The following explanation seems simpler to me. A bass note that is not also the root seems to strive to assert its overtones—in other words, to become the root itself. As shown earlier, on page 69, the bass of the six-four chord receives ample support for this…

Preparation of the six-four chord differs from preparation of a dissonance in that either of two notes may be considered. One can prepare either the fifth, that is, the bass note, or the root: one of these two notes should have belonged to the preceding chord…

The D of the six-four chord on V could be preceded only by D, E, or C in the bass. An E bass could mean degree III, the sixth chord on I, or the six-four chord on VI. E with a six-four is ruled out from the outset, since otherwise two six-four chords would…
