On abowed string instrument, abow stroke is the movement of thebow back and forthperpendicularly across thestring, from the frog to the tip and from the tip to the frog, producingsound. Multiplenotes in one bow stroke are indicated by the use ofslurs.
Adown-bow is a type of stroke used when bowing amusical instrument, most often astring instrument. The player performs the indicated note by drawing thebow downward or to the right across the instrument, moving its point of contact from the frog toward the tip of the bow. This technique is indicated by a notated symbol resembling a small bracket over the note.[1][2]
How the down-bow is achieved varies depending on the shape and orientation of the instrument. Onviolin andviola, the player pulls the bow down, away from the left shoulder. Oncello anddouble bass, the player pulls the bow to the right, away from the left elbow.
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.
Anup-bow is a type of stroke used when bowing amusical instrument, most often astring instrument. The player draws thebow upward or to the left across the instrument, moving the point of contact from the bow's tip toward the frog (the end of the bow held by the player).[3][2]
How the up-bow is achieved varies depending on the shape and orientation of the instrument. Onviolin andviola, the player pushes the bow up, toward the left shoulder. Oncello anddouble bass, the player pushes the bow to the left, toward the left elbow
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.
