Double bell euphonium

The double bell euphonium is a duplex instrument based on the euphonium. The larger bell produces the mellow tone of a standard euphonium; the second smaller bell has a brighter tone, similar to a baritone horn or valve trombone. The instrument is sometimes dismissed as a novelty, but has had some enthusiastic adherents, including a few professional musicians using it as their sole or primary instrument. The smaller bell can give more appropriate tone in the higher range of the instrument.
