The bass trumpet is about twice as long as the standard instrument and has a similar range to the trombone. The most significant bass trumpet part in the orchestra repertoire is in Wagner's opera cycle Der Ring des Nibelungen. This instrument was probably made for Jesse Stamp, who would have performed on it at concerts of Wagner excerpts at the Proms. The instrument was later owned by the trombonist Harold Nash, who used it in performances of the complete Ring Cycle at the Royal Opera House in Covent Garden.
