Street musician playing Hang and didgerydoo at Anděl. The Hang or "bowl drum" is a musical instrument in the idiophone class created by Felix Rohner and Sabina Schärer in Bern, Switzerland. The Hang is sometimes referred to as a hang drum. 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 a distinct 'UFO shape'. The top side has a center 'note' hammered into it and seven or eight 'tone fields' hammered around the center. The bottom 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.[8] The inventors of the Hang have continued to refine the shape and materials and have produced several variations over the years.
