V. SHIFTING (sometimes known as “vomit”) – It’s time to move through the whole keyboard. We’ll use A major on the G string, for two octaves. Don’t repeat the top note. The first finger listed is always on the drone note, the second finger listed shifts to the scalar note. Each combination goes through the entire 2 octave sequence. At mm=60 this can take 45 min. to do it in entirety. This is a chance to examine speed in shifting (slow to fast), ghosting in lower finger reference notes (slide and drop to new finger, or on downward shifts, slide and lift to the new finger.), replacing fingers during a shift, arm and back motion, bow speed in relation to pitch – and more. Great finger strengthener if you stay on your tips and keep the curl.
Fingerings: (1-1, 1-2, 1-3, 1-4) (2-1, 2-2, 2-3, 2-4) ( 3-1, 3-2, 3-3, 3-4) ( 4-1, 4-2, 4-3, 4-4)
A. Shifting across strings – Use the dominant on the lower string as a drone while using the fingering as above.
B. “Super Vomit”. Go to the highest point of the scale as prescribed above, then let the TOP tonic be the drone note with the upper finger while descending through the scale with the lower finger, when you reach the top again – finish as in regular vomit. Twice as long.
ADVICE: This is a bow-speed exercise. Low pitches get less bow than higher pitches. Stay at the low note speed until you reach the higher note. When shifting down, immediately change to the lower speed. Stretch the back on the left side as you shift up. ONLY the finger tips of the left arm should be touching the bass.
