Play the excerpt from Kruetzer No. 7.
Play a small but powerful "T" consonant at the tip by throwing the bow up-bow with the biceps (about 4 inches).Then do the same down-bow at the frog by using the triceps to throw the bow down-bow (again about 4 inches). Start with open strings until you get the motion right
The fingers should be straight at the tip ready to be thrown up bow.
The fingers should be round (especially the pinky) at the frog ready to throw the bow down.
Prepare the hand to be thrown in either direction before moving the bow.
Always imitate the hard consonant sound of the "T".
Play slowly witn no metronome and away from the bridge
