PINCHAS ZUKERMAN'S CHANGE OF POSITION TECHNIQUE
There are as many techniques in changing position as there are violinists, the rarest forms can be found in both beginners and the most famous violinists. Far from judging and qualifying the performer's conscious and unconscious choice, the commonalities in the human physiognomy allow us to find ways to make changes in position that may be more comfortable for the performer in general. The video to be analyzed corresponds to Elgar's violin concerto with the Berliner Philharmoniker with Pinchas Zukerman as soloist. The system used for the analysis will be the usual one, using the Kinovea software as a motion analyzer tool, which semiautomatically detects the movements on which we decide to focus. The reference points that we will take into account will be mainly the metacarpophalangeal joint of the thumb and forefinger, using the carpometacarpal joint as the axis of the angle formed by these two ends. These three points will allow us to distinguish the position of the thumb with regard to the other fingers of the hand and the degree of the angle of the lower space between the hand and the handle, all at different points in time.
