Harmonics

Both natural and artificial harmonics and discussed and demonstrated here.

Harmonics

Natural Harmonics are produced whilst bowing, with a finger of the left hand the player lightly touches the string at a nodal point. This produces a light, "fluted" sound. Notation: a small circle above the note. Artificial harmonics are produced when the string is stopped normally, and then fingered lightly (with the little finger) at a point a 4th or a 5th above the stopped note. . Sometimes flag (= flageolet) is written over the note. It is possible to add vibrato and to play melodic lines in artificial harmonics, but both techniques should be used with care.
