Hang (musical instrument)
Hang is a melodious percussive steel musical instrument created in Switzerland. It uses some of the same physical principles as a steel drum. That being said there has been much metallurgical and acoustic research by the makers which have led to significant changes in structure, design, and process.
It was the result of many years of research on the steelpan as well as the study of a diverse collection of instruments from around the world; such as gongs, gamelan, ghatam, drums, bells, etc. Udu-like sounds can be produced with the Helmholtz resonance that can occur within the clamped shallow shells. It also has the capacity to ring like a singing bowl. The instrument has sometimes been referred to by owners and others as a hang drum, because it is often played like a drum, its relation to the steel drum, and its popularity with hand drummers. While this is true, there are other ways to coax sound out of a Hang that do not involve 'drumming'.
