The alto trombone (German: Altposaune, Italian, French: trombone alto) is the alto member of the trombone family of brass instruments, smaller than the tenor trombone. It is almost always pitched in E♭ a fourth higher than the tenor, although examples pitched in F are occasionally found. The alto trombone was commonly used from the 16th to the 18th centuries in church music to strengthen the alto voice, particularly in the Mass.^[1] Alto trombone parts are usually notated in alto clef.
