With an independent system, the first valve still lowers the key to F, but the second valve commonly lowers the key to G when engaged alone or D when engaged with the first valve. 19th and early 20th century examples of the modern bass trombone were sometimes made with a valve attachment in E rather than F, or with an alternative tuning slide for the attachment tubing enabling the pitch to be lowered to E. Bore sizes of the bass trombone are generally larger than those of large bore tenor trombones. Typical specifications include a bore size of in the slide and through the valve attachment tubing, with a bell from in diameter. Bass trombones with just one valve often have a long tuning slide which allows the valve to change the key to E rather than the usual F. 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. There is usually one bass trombone in a standard symphony orchestra performing works in the Romantic period or later. It is also seen in military bands, brass bands, jazz bands, wind ensembles, and a variety of brass groups; the bass trombone is usually played by the third trombonist in a symphony orchestra trombone section, the first two parts usually being played by tenor trombones. In jazz, the most notable uses of the bass trombone are in two of pianist Herbie Hancock's recordings, "Speak Like a Child" (1968) and "The Prisoner" (1969), which employed the instrument for purely voicing purposes. Older, now obsolete versions of the bass trombone were of smaller bore than the modern bass trombones described above. They were usually pitched in G, F, or E, and had a longer slide with a handle attached to the outer slide stay to allow for full extension of the slide. They were mainly used in Europe and the British Empire.
