here's a bit more:

Quote:

As a Violinist, Wolf is a standard term to describe either a bad sound
from ONE note or a double stop (a two note chord).
Specifically, in the one note version, it will generally be activated (providing the anomaly exists) in the range of C above open G to about G above open G. Its effect is caused by a flaw in the mechanical structure of the violin which produces a large resonance brought about by the weakness in the related structural parts which cause a howling or barking sound. In the case of wolf tones in double stops, the effect is a production of a third tone (which shouldn't be there) in this case, it is usually less howling and rather more soft. Maybe wolf was a good description because on the Violin it really does wolf or howl.
