Contrabass trumpet
Musical instrument
The contrabass trumpet is the lowest-pitched member of the trumpet family, sounding below the bass trumpet. Only a few exist. The instrument appeared in the mid-20th century and has no orchestral or jazz repertoire.[1] Usually built in 12' F a perfect fourth below the B♭ bass trumpet, it has the same length as the F contrabass trombone, cimbasso, or tuba. Some (sometimes called the subcontrabass trumpet) are built larger in 18' B♭— an octave below the bass trumpet and two octaves below the standard B♭ trumpet.
