(Valved aerophone sounded by lip movement)
The sousaphone is a specialized version of the helicon. The original sousaphone produced by the J.W. Pepper Company had an upright bell, hence the nickname "raincatcher". Later versions differ primarily in two ways: a bell shaped to face forwards with a larger flare, and a bell diameter of 22 to 28 inches, and a "goose-neck" leadpipe which offers greater adjustability of mouthpiece position at the expense of tone quality, while both instruments have circular shapes and are designed to be worn on the shoulder.
The instrument is very popular in Central and Eastern Europe and is a common choice for military fanfares. It is used by Ed Neuhauser of the traditional folk band Bellowhead.
The German manufacturer Melton developed these instruments using the acoustical proportions of the supremely mighty Červený Imperial BB♭ Contrabass Helicon:
- Soprano in E♭
- Alto in B♭
- Tenor in E♭
- Baritone in B♭
- Bass in F (or EE♭)
- Contrabass in BB♭ (or CC)
