The Vibrato or close shake
is a trembling similar to the vibrato of a vocalist. Employed occasionally and with discretion it is of good effect. On the violin it is produced by setting the finger in tremulous movement upon the string, so that the pitch slightly rises and falls. Only the thumb and the finger in use must participate in the holding of the instrument. There is no special sign for the close shake in general use, its employment depending upon the player’s taste. Sometimes it is indicated by the word vibrato.[17]
