An aerophone is any musical instrument which produces sound primarily by causing a body of air to vibrate, without the use of strings or membranes, and without the vibration of the instrument itself adding considerably to the sound. It is one of the four main classes (class 4) of instruments in the original Hornbostel-Sachs scheme of musical instrument classification. The other three are idiophone, membranophone and chordophone. A fifth class, electrophone, was added in a later revision. A musical instrument is a device that has been constructed or modified with the purpose of making music. ... A schematic representation of auditory signaling Sound is vibration, as perceived by the sense of hearing. ... A membrane is a thin, typically planar structure or material that separates two environments. ... Hornbostel-Sachs (or Sachs-Hornbostel) is a system of musical instrument classification divised by Erich Moritz von Hornbostel and Curt Sachs, and first published in the Zeitschrift für Musik in 1914. ... At various times, and in various different cultures, various schemes of musical instrument classification have been used. ... An idiophone is any musical instrument which creates sound primarily by way of the instrument itself vibrating, without the use of strings or membranes. ... A membranophone is any musical instrument which produces sound primarily by way of a vibrating stretched membrane. ... A chordophone is any musical instrument which produces sound primarily by way of a vibrating string or strings stretched between two points. ... An electrophone is any musical instrument which produces sound primarily by electrical means. ...


Hornbostel-Sachs divides aerophones by the fact whether vibrating air is contained in the instrument itself or not.


The first class (41) includes instruments where the vibrating air is not contained by the instrument itself, such as the bullroarer. Such instruments are called free aerophones. This class includes free reed instruments, such as the harmonica, but also many instruments unlikely to be called wind instruments at all by most people, such as sirens and whips. A bullroarer or turndun is a primitive ritual musical instrument and means of communicating over extended distances. ... ... A harmonica A harmonica is a free reed musical wind instrument (also known, among other things, as a mouth organ, french harp, simply harp, or Mississippi saxophone), having multiple, variably-tuned brass or bronze reeds, each secured at one end over an airway slot of like dimension into which it... Sirens are devices making sound to alarm others, such as the air raid siren or the sirens on emergency service vehicles such as ambulances, police cars and fire engines. ... The whip or slapstick is a percussion instrument consisting of two wooden boards joined by a hinge at one end. ...


The second class (42) includes instruments where the vibrating air is contained by the instrument. This class includes almost all the instruments generally called wind instruments in the west, such as the flute, the oboe and the trumpet. A wind instrument consists of a tube containing a column of air which is set into vibration by the player blowing into (or over) a mouthpiece set into the end of the tube. ... This article pertains to the musical instrument. ... Modern Oboe The Oboe is a musical instrument of the woodwind double reed family. ... Trumpeter performing with the United States Air Forces in Europe Band The trumpet is the highest brass instrument in register, above the tuba, euphonium, trombone, sousaphone, and french horn. ...


Additionally, very loud sounds can be made by explosions directed into, or being detonated inside of resonant cavities. Instruments such as the calliope (and steam whistle), as well as the pyrophone might thus be considered as class 42 instruments, despite the fact that the "wind" or "air" may be steam or an air-fuel mixture. A pyrophone, also known as a fire/explosion organ or fire/explosion calliope is a musical instrument in which notes are sounded by explosions, or similar forms of rapid combustion, rapid heating, or the like. ...
