Hang

The Hang ( German pronunciation: [haŋ]; plural form: Hanghang) is a type of musical instrument fitting into the idiophone class and based on the Trinidad & Tobago steelpan. It was created by Felix Rohner and Sabina Schärer in Bern, Switzerland, and marketed by their company, PANArt Hangbau AGa. They took the name "Hang" from a Bernese German word that means both "hand" and "hillside". Though it has sometimes been referred to as a "Hang drum", the inventors consider this a misnomer.

The Hang is constructed from two half-shells of deep-drawn, nitrided steel sheet glued together at the rim, leaving the inside hollow and creating the shape of a convex lens. The top ("Ding") side has a center 'note' hammered into it and seven or eight 'tone fields' hammered around the center. The bottom ("Gu") is a plain surface that has a rolled hole in the center with a tuned note that can be created when the rim is struck. The instrument uses some of the same basic physical principles as a steelpan, but modified in such a way as to act as a Helmholtz resonator.
