Alphabetical list of musical instruments

Musical Instrument List
Using this classification system (Hornbostel-Sachs), plus additions for not yet classified instruments, World University and School hopes to facilitate a COMPLETE list of world instruments, with a musical instrument template like its SUBJECT TEMPLATE - http://worlduniversity.wikia.com/wiki/SUBJECT_TEMPLATE - with jamming possibilities in virtual worlds, potentially, here. (This classification may become a key way to structure the Music school's database).

Please add instruments in the categories below.

Idiophones (1)
Idiophones - sound is primarily produced by the actual body of the instrument vibrating, rather than a string, membrane, or column of air. In essence, this group includes all percussion instruments apart from drums, as well as some other instruments. In the Hornbostel-Sachs-classification idiophones are firstly categorized according to the method used in playing the instrument. This results in four main categories: struck idiophones (11), plucked idiophones (12), friction idiophones (13), and blown idiophones (14). These groups are subsequently divided through various criteria. In many cases these sub-categories are split in singular specimens and sets of instruments. The latter category includes the xylophone, the marimba, the glockenspiel, and the glass harmonica. List of idiophones by Hornbostel-Sachs number.

Struck idiophones (11)
These idiophones are set in vibration by being struck, for example cymbals or xylophones.

Directly struck idiophones (111)
The player himself executes the movement of striking; whether by mechanical intermediate devices, beaters, keyboards, or by pulling ropes, etc. It is definitive that the player can apply clearly defined individual strokes and that the instrument itself is equipped for this kind of percussion.


 * 111.1 Concussion idiophones or clappers - Two or more complementary sonorous parts are struck against each other.
 * 111.11 Concussion sticks or stick clappers.
 * 111.12 Concussion plaques or plaque clappers.

 * 111.14 Concussion vessels or vessel clappers.
 * 111.141 Castanets - Natural and hollowed-out vessel clappers
 * 111.142 Cymbals - Vessel clappers with manufactured rim.
 * 111.2 Percussion idiophones - The instrument is struck either with a non-sonorous object (hand, stick, striker) or against a non-sonorous object (human body, the ground).
 * 111.21 Percussion sticks.
 * 111.211 Individual percussion sticks.
 * 111.212 Sets of percussion sticks in a range of different pitches combined into one instrument. - All Xylophones, as long as their sounding components are not in two different planes.

 * 111.242.122 Sets of hanging bells with internal strikers.

Indirectly struck idiophones (112)
The player himself does not go through the movement of striking; percussion results indirectly through some other movement by the player.
 * 112.1 Shaken Idiophones or rattles - The player makes a shaking motion
 * 112.11 Suspension rattles - Perforated idiophones are mounted together, and shaken to strike against each other.
 * 112.111 Strung rattles - Rattling objects are strung in rows on a cord.
 * 112.112 Stick rattles - Rattling objects are strung on a bar or ring.
 * 112.12 Frame rattles - Rattling objects are attached to a carrier against which they strike.
 * 112.121 Pendant rattles.
 * 112.122 Sliding rattles.
 * 112.13 Vessel rattles - Rattling objects enclosed in a vessel strike against each other or against the walls of the vessel, or usually against both.


 * 112.2 Scraped Idiophones - The player causes a scraping movement directly or indirectly; a non-sonorous object moves along the notched surface of a sonorous object, to be alternately lifted off the teeth and flicked against them; or an elastic sonorous object moves along the surface of a notched non-sonorous object to cause a series of impacts. This group must not be confused with that of friction idiophones.

Plucked idiophones (12)
Plucked idiophones (lamellophones) - idiophones set in vibration by being plucked, for example the Jew's harp or thumb piano. This group is sub-divided in the following two categories

In the form of a frame (121)

 * 121.1 Clack idiophones or Cricri - The lamella is carved in the surface of a fruit shell, which serves as resonator.

Chordophones (3)
Chordophones - sound is primarily produced by the vibration of a string or strings that are stretched between fixed points. This group includes all instruments generally called string instruments in the west, as well as many (but not all) keyboard instruments, such as pianos and harpsichords. List of chordophones by Hornbostel-Sachs number

Simple chordophones or zithers (31)
Instruments which are in essence simply a string or strings and a string bearer. These instruments may have a resonator box, but removing it should not render the instrument unplayable (although it may result in quite a different sound being produced).

Aerophones (4)
Aerophones - sound is primarily produced by vibrating air. The instrument itself does not vibrate, and there are no vibrating strings or membranes. List of aerophones by Hornbostel-Sachs number

Free aerophones (41)
Instruments where the vibrating air is not enclosed by the instrument itself, for example sirens, or the bullroarer. The vibrating air is not contained within the instrument.

Displacement free aerophones (411)
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)
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 - Accordion, Harmonica.
 * 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. - (British Columbia.)
 * 412.2 Non-idiophonic interruptive instruments.
 * 412.21 Rotating aerophones.
 * 412.22 Whirling aerophones.

Plosive aerophones (413)
The sound is caused by a single compression and release of air.

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