The "Claude Thornhill Orchestra" was moderately successful before World War II, and after the war, Thornhill re-formed the orchestra with Gil Evans as chief arranger and musical director. The original instrumentation of the band in 1946 was 4 trumpets, 3 trombones, 5 reeds and rhythm section. By the time La Paloma was arranged in June of 1947, the brass section consisted of 3 trumpets, 2 trombones, tuba, 5 reeds and rhythm. The source for this publication is Evans' original score. This is a great opportunity to feature your piano player. Ranges: Trumpet 1 to C#6; Trombone 1 B4.
