"Violin mastery? There have been only three violinists within my own
recollection, whom I would call masters of the violin. These are
Kubelik (when at his best), Franz von Vecsey, Hubay's pupil, whom I
heard abroad, and Heifetz, with his cameo-like perfection of technic.
These I would call masters of the violin, as an instrument, since they
have mastered every intricacy of the instrument. But I could name
several others who are greater musicians, and whose playing and
interpretation, to say nothing of tone, I prefer.
