Contrabass Trombone

The contrabass trombone is a huge trombone pitched an octave below the normal tenor and bass trombones. The mouthpiece is obviously much larger than that of the bass trombone. Almost the size of a tuba mouthpiece. Bb1 is a normal note on this trombone and although note clear all the time and really hard to center this trombone can play all of the way down to E0. There are many different variations of the contrabass trombone but the most common of these rare instruments is in the key of BBb with an F attachment. Many even have a double wrapped slide like the one above.

This trombone is rarely used because of complexity of the instrument and the tuba, which can play all of the notes that this trombone can play. When used this trombone is usually used in orchestras and may have only one notes in a whole concert.
