The Bass Trumpet extends the range of the trumpet section into the low register. There are instruments in Bb, C, Eb and even D and F. In Europe the bass trumpet in C is the most common.

For the euphonium player venturing into the realms of orchestral playing, the bass trumpet presents itself as a further possibility. In works such as „The Ring“ (Wagner), „Elektra“, „MacBeth“ (R. Strauss), „Gurre-Lieder“ (Schoenberg), „The Rite of Spring“ (Stravinsky) etc. the bass trumpet has a very prominent part.
