Edge-Blown Aerophones

Edge-blown aerophones is one of the categories of musical instruments found in the Hornbostel–Sachs system of musical instrument classification. In order to produce sound with these aerophones, the player makes a ribbon-shaped flow of air with their lips (421.1), or their breath is directed through a duct against an edge (421.2). 421.1 Flutes without duct – The player creates a ribbon-shaped stream of air with their lips.
