THE BASICS REVISITED: ARTISTIC DISTINCTIONS

B. On each finger, play a whole note (two vibrato cycles per beat). Be sure to maintain accuracy with the metronome. v n v n 3 4 I 2 .0. 0 .g. liB e

IY. CHANGING VIBRATO WIDTH Use the exercise below to practice changing the width of the vibrato. Practice each exercise in the following manner: Quarter= 60 1, 2, 3, 4, and 6 vibrato cycles per beat Try to maintain a contact point near the bridge, making the crescendo and decrescendo through varying bow speed and weight. Note that in each beat the combination of fingertip, hand, forearm, and upper arm changes.

V. To DEVELOP HAND VIBRATO Each of the following rhythms represents two vibrato cycles, with the pitch change being repre sented by an articulated subdivision. Initially, practice this exercise in third position with the forearm secured against the instru ment and the wrist flexible. Try to drop the pitch by a quarter step in the vibrato swing. Start by repeating the pattern 4 times before changing fingers. Vary the exercise by connecting from finger to finger within a position, applying to every fin ger in every position, and on the same finger, connecting from position to position while con tinuing on that same finger. Quarter = 92
