The Hang (often mistakenly called a 'handpan') was created in Bern, Switzerland, by Felix Rohner and Sabina Schärer of PANArt in 2000. It is a percussion instrument consisting of two deep-drawn, nitrided steel shells glued together at the rim, leaving the inside hollow. The top side, called the 'Ding,' has a center note and seven or eight 'tone fields' hammered into it. The bottom side, called the 'Gu,' has a hole in the center that acts as a Helmholtz resonator. The Hang is played with the hands and fingers rather than mallets, allowing for a vast range of textures and overtones. The instrument became a viral sensation due to its ethereal, bell-like sound. However, the original creators stopped producing the 'Hang' in its original form to focus on other 'Gubal' instruments, leading to a worldwide surge in other manufacturers creating similar instruments now collectively known as handpans.
