A Hang is a harmonically tuned steel idiophone created by PANArt in Switzerland. It uses some of the same physical principles as a steelpan but with a nitrided surface and structural change of having two clamped shells with a small opening so that the instrument is a Helmholtz Resonator. The creation of the Hang 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/udu, drums, and bells. Metallurgical and acoustic research by the makers has led to significant changes and refinement in structure, design, and process over the years since the first Hang was offered. The instrument is often referred to as a Hang drum, because it is often played like a drum due to its popularity with hand drummers. There are many ways to coax sound out of a Hang that do not involve 'drumming'. The creators discourage the drum label, but instead tend to refer to it as a "sound sculpture", which could be considered appropriate as it has sculptural/architectural elements as well as sonic ones. source wiki: en.wikipedia.org
