The range of the modern bass trombone is fully chromatic from the lowest fundamental with the valve attachment tubing deployed. A bass trombone with the second valve in G is capable of playing from a B0 (or even A0 with valve slides extended), up to C5 – many professionals are capable of extending the range even higher, though such demands may be taxing and/or unreliable to the player. Older or more conservative compositions often shy away from extremes, and will infrequently stray above an F4/G4 or below a B1. Contemporary orchestral and solo classical pieces, as well as modern jazz arrangements, will often further exploit the wide tonal range of the bass trombone.
