List of aerophones by Hornbostel-Sachs number

The Hornbostel-Sachs system of musical instrument classification groups all instruments in which sound is produced through vibrating air. This can include a column of air being set in vibration (as in wind instruments) or an air-flow being interrupted by an edge (as in free-reeds).

41. Free aerophones

The vibrating air is not contained within the instrument.
*Klaxon
*Bullroarer
*Siren
*Lasso d'amore

412.13. Free-reed instruments

Free-reed instruments feature a reed which vibrates within a closely fitting slot (there may be an attached pipe, but it should only vibrate in sympathy with the reed, and not have an effect on the pitch - instruments of this class can be distinguished from 422.3 by the lack of finger-holes).
*Accordion
*Bandoneon
*Concertina
*Harmonica
*Harmonium
*Melodica
*Reed organ
*Sheng

413. Plosive aerophones

The sound is caused by a single compression and release of air.
*Udu "drum" or kimkim
*Boomwhacker
*End-struck pipe-based instruments, variations on earlier known instruments recently popularized by Blue Man Group, in forms that they refer to as Tubulum, Drumbone, etc.

42. Non-free aerophones (wind instruments proper)

The vibrating air is contained within the instrument.

421. Edge-blown instruments or flutes

The player makes a ribbon-shaped flow of air with his lips (421.1), or his breath is directed through a duct against an edge (421.2).
*Conch shell (if played like a flute)
*Flue pipe of an organ
*Flute
*Hocchiku
*Huaca
*Jug

422. Reed instruments

The player's breath is directed against a lamella or pair of lamellae which periodically interrupt the airflow and cause the air to be set in motion.
