Wind machine
type of musical instrument
The wind machine (also called an aeoliphone or aelophon) is a friction idiophone used to produce the sound of wind for orchestral compositions and musical theater productions.
Construction
The wind machine is constructed of a large cylinder made up of several wooden slats which measures approximately 75–80 cm (30–31 in) in diameter. The cylinder body of the instrument rests upon a stand and is typically covered with silk, canvas, or other material which is in a fixed position. A crank handle, used by the player to rotate the cylinder and create the sound, is attached to the cylinder.
Another method of construction implements an electric fan, which is fitted with lengths of cane, rather than blades. However, this method is less popular because it does not provide the player with the ability to control the speed of rotation.
Technique
The wind machine is played by rotating the crank handle, which is attached to the cylinder, to create friction between the wooden slats and the material covering that touches the cylinder but does not rotate as the crank handle is turned. This friction between the wood and the material covering creates the sound of rushing wind. The volume and pitch of the sound is controlled by the rate at which the crank is turned. The faster the handle is turned, the higher the resulting pitch and the louder the sound.
Begin with the source’s own compact description: “Wind machine” is type of musical instrument. The dossier treats that line as a proposition to test through Wind, machine and type, not as a finished interpretation.
Why this record matters
The phrase “type of musical instrument” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q290688. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
