Hangul supremacy
Hangul supremacy is the belief, most widespread in Korea, that the Hangul alphabet developed by King Sejong the Great's Hall of Worthies in 1443 is the simplest, most logical, most beautiful and most scientific of the world's writing systems. In its extreme form, the belief holds that Hangul is in fact best suited for the expression of sounds in all languages.
Hang (instrument)
The Hang (; 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.
