Creation and Development
The Hang was developed in the year 2000 and introduced at the Musikmesse Frankfurt in 2001. It is 52 cm in diameter and has a height of 24 cm. The two deep drawn steel hemispheres of the Hang are hardened by a process known as gas-nitriding. The side considered the 'bottom' has an opening (Gu) in the center which allows the generation of the bass note through Helmholtz resonance. When it is played in a damped way it can change in pitch similar to a talking drum. On the 'top' are seven or eight notes arranged in a tone circle in zig-zag fashion from low to high. All are tuned harmonically (with fundamental, octave and the fifth above the octave) around a low note (Ding) at the center of the tone circle. Each creation is numbered and signed.
There are only two people who build Hanghang, the inventors Felix Rohner and Sabina Schärer. They have a little workshop in Bern where every Hang has been created.

Famous quotes containing the words creation and/or development:
“The human spirit is itself the most wonderful fairy tale that can possibly be. What a magnificent world lies enclosed within our bosoms! No solar orbit hems it in, the inexhaustible wealth of the total visible creation is outweighed by its riches!”
—E.T.A.W. (Ernst Theodor Amadeus Wilhelm)
“Women, because of their colonial relationship to men, have to fight for their own independence. This fight for our own independence will lead to the growth and development of the revolutionary movement in this country. Only the independent woman can be truly effective in the larger revolutionary struggle.”
—Women’s Liberation Workshop, Students for a Democratic Society, Radical political/social activist organization. “Liberation of Women,” in New Left Notes (July 10, 1967)
