List of aerophones by Hornbostel–Sachs number

(Redirected from List of musical instruments by Hornbostel-Sachs number: 412)

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). The instrument itself does not vibrate, and there are no vibrating strings or membranes.

Aerophones (4)

edit

Free aerophones (41)

edit

Instruments where the vibrating air is not enclosed by the instrument itself.

Displacement free aerophones (411)

edit

The air-stream meets a sharp edge, or a sharp edge is moved through the air. In either case, according to more recent views, a periodic displacement of air occurs to the alternate flanks of the edge. Examples are the swordblade or the whip.

Interruptive free aerophones (412)

edit

The air-stream is interrupted periodically

412.1 Idiophonic interruptive aerophones or reeds - The air-stream is directed against a lamella, setting it in periodic vibration to interrupt the stream intermittently. In this group also belong reeds with a 'cover,' i.e. a tube in which the air vibrates only in a secondary sense, not producing the sound but simply adding roundness and timbre to the sound made by the reed's vibration; generally recognizable by the absence of fingerholes.

412.11 Concussion reeds - Two lamellae make a gap which closes periodically during their vibration.

412.12 Percussion reeds - A single lamella strikes against a frame.

412.121 Independent percussion reeds.

412.122 Sets of percussion reeds. - Earlier organs

412.13 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).

412.131 Individual free reeds.

412.132 Sets of free reeds.

412.14 Band reed instruments - The air hits the sharp edge of a band under tension. The acoustics of this instrument have so far not been investigated.[1]

412.2 Non-idiophonic interruptive instruments.

412.21. Rotating aerophones (the interruptive agent rotates in its own plane and does not turn on its axis)

412.22. Whirling aerophones (the interruptive agent turns on its axis)

Plosive aerophones (413)

edit

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.

Non-free aerophones (wind instruments proper) (42)

edit

The vibrating air is contained within the instrument. This group includes most of the instruments called wind instruments in the west, such as the flute or French horn, as well as many other kinds of instruments such as conch shells.

Edge-blown aerophones or flutes (421)

edit

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).
