A careful, step by step approach to properly using the F attachment on the tenor and bass trombone. Intended for tenor players who have never used an F attachment horn or who have not been properly instructed on its use. Focuses also on uncommon F positions, such as 5th, 6th and flat 7th. A short section at the end deals with maintaining the rotor valve. Written by a highly respected veteran trombone educator who used these materials in his own studio. 48 pages. -cdp
