18th Century violinist-composer Pierre Gavinies, once described by Viotti as the "French Tartini," was certainly a violinist of great skill, if his virtuosity may be judged from his printed legacy. His 24 Studies (Matinees) for solo violin cover all 24 keys and a wide variety of techniques. Because of this, and because of the difficulty of the studies, they are highly regarded in the violin community, and taken as prescribed medicine by advanced violinists the world over. This edition of the 24 Studies is edited by Ivan Galamian. Published by the International Music Company.
