Twenty One Studies (trombone)

"Written by Gerard Pichaureau, Twenty-one studies is a set of difficult studies for Trombone. Of one page each, these studies are written in the keys of C and F, and should help improve general techniques already acquired. It would work very well being followed by the Twenty studies.   Gerard Pichaureau is a French Trombonist and composer. As a professor at the Paris Conservatoire, he wrote a number of sets of studies such as 'Twenty studies', 'Thirty studies in all keys' and 'Special Legato'."
