Note 12 — PART II. The technique of violin playing.
John Matthews translation
The real “holding”—as regards the weight of the instrument—is done at the other end by the chin pressing the violin against the collar bone. What further steadying power is necessary, the lower joint of the thumb must supply, rather than the first finger. Players who have attained considerable freedom are able to play certain passages without any portion of the side of the index finger coming into contact with the neck. Chin-rests of various patterns should be tried, and that which best suits the particular player selected, as bodily proportions differ. Tr.
