Instruments

How the down-bow is achieved varies depending on the shape and orientation of the instrument.

Uses

String players can exert stronger pressure when bowing near the frog than when bowing near the tip, due to the bowing hand's proximity to the bow's contact point with the string. Down-bows, which begin near the frog, are therefore often used to play the downbeat (strong beat) within musical phrases. Notes that begin loudly and diminuendo are ideally down-bowed — from frog to tip — allowing pressure on the string to decrease naturally.

String players can exert stronger pressure on the string when bowing near the frog than when bowing near the tip, due to the bowing hand's proximity to the bow's contact point with the string. Up-bows, which begin near the tip, are therefore often used to play the upbeats (weaker beats) within a musical phrase. Notes that begin quietly and crescendo are also ideally up-bowed — from tip to frog — allowing pressure on the string to increase naturally.
