This work was written at the suggestion of Denis Wick to show some of the range, flexibility and variety of the trombone quartet which has to date drawn from composers music of a predominantly sombre and static character. The combination written for is two tenor and two bass trombones (TTBB). However, all movements except number 3 can be played by three tenors and 1 bass (TTTB). --the composer (June 1970) Note: In actuality, all four movements can be played by TTTB trombone or even 4 tenors (TTTT). --cdp
