Rudolf Matz (1901-1988) was a longtime cellist, composer, and pedagogue in his native Croatia. He was lauded by Janos Starker and Leonard Rose, who called him "perhaps the greatest cello theoretician in the world." His most important contributions to cello pedagogy are in building technique in the all-important early years of musical development.
Matz's 54 Short Etudes for Young Hands are designed with young, smaller, and less developed hands in mind. They provide an introduction to standard technical exercises in open and raised positions.
