hang

The Hang (German pronunciation: [haŋ]; plural form: Hanghang) is a musical instrument in the idiophone class created by Felix Rohner and Sabina Schärer in Bern, Switzerland. The name of their company is PANArt Hangbau AG. The Hang is sometimes referred to as a hang drum, but the inventors consider this a misnomer and strongly discourage its use.The instrument 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 Hang uses some of the same basic physical principles as a steelpan, but modified in such a way as to act as a Helmholtz resonator. The creation of the Hang was the result of many years of research on the steelpan and other instruments. The inventors of the Hang have continued to refine the shape and materials and have produced several variations over the years.
The name Hang comes from a Bernese German word which has a double-meaning, one of which is hand and the other hillside referring to its convex shape. It is a registered trademark and property of PANArt Hangbau AG.Growth of a worldwide interest in the Hang created a group of similar instruments which are referred to as handpans, a term coined in 2007 by the American steelpan producer Pantheon Steel.
