If down-bow and up-bow alternate continuously this is the most natural pattern and does not need to be marked.
All notes included under a single slur will be played by one bow.
If a phrase begins with an up-beat or anacrusis it is understood without marking that it will be played up-bow. If down-bow is preferred it must be indicated.
Any desired deviation from the regular alternation of down-bow and up-bow must be marked accordingly.
Separated notes with dots indicate varied types of staccato which must be defined for the player by further description in Italian: spiccato, saltato, martele; or by the English meaning: "rapidly and lightly," "jumping bow," "hammered," etc.
Separate notes with dots may be included in a slur, with the type of dot indicating intensity of articulation.
Whenever dots are used under a slur to indicate successive down-bows or successive up-bows, or whenever any deviation
from the normal alternation is brought into the phrasing, mark indications for the bowing which will return it as soon as possible to the normal alternation (down-bow, up-bow).
