There are several overlapping schemes for the classification of percussion instruments .
These schemes are based on four types of criteria:
Percussion instruments vary enormously in nature and usage, and have possibly the longest history of any group of musical instruments. [1] For these and other reasons their classification proves difficult, and different classification systems are used in different contexts.
At the highest level of grouping, authorities differ over whether stringed instruments such as the hammered dulcimer and keyboard instruments such as the celesta are percussion instruments, let alone the piano which is both stringed and a keyboard and yet sometimes also termed percussion. [2] [3]
Hornbostel–Sachs does not use the term percussion as a general grouping at all, but instead in a very different sense to the common usage. Instruments such as castanets and cymbals used in pairs are not percussion in the Hornbostel–Sachs sense, but are percussion instruments in every other sense.
Similar problems are encountered at lower levels of classification.
Ancient Chinese and Indian systems of classification were based on the materials of which the instruments were constructed, and the acoustic properties of the instruments, respectively.[ citation needed ]
In the 14th century Jean de Muris produced a classification system which divided all musical instruments into three classes: Percussion, String and Wind.[ citation needed ] Hornbostel–Sachs further develops this scheme, but abandons the percussion high-level grouping, replacing it by the groups idiophones and membranophones.
Hornbostel–Sachs classifies musical instruments by means of a numerically labelled inverted tree structure, originally with four groups at the highest level, two of which are percussion instruments (as the term percussion is normally understood), and the others strings and wind. The system does use the term percussion but at a much lower level in the tree and in an esoteric sense quite unlike its common usage, see below.
Some of the important percussion groupings are:
For a complete list of idiophone classes see:
Hornbostel–Sachs does not distinguish between pitched and unpitched instruments at any level.
It should be particularly noted that this classification does not use the term percussion in its high level grouping, but instead in an esoteric sense, so that other instruments such as the clarinet that are not percussion in any normal sense are described as percussion reeds .
Having no explicit category for percussion as normally understood, Hornbostel–Sachs places nearly all percussion instruments in the high level categories of membranophones (high-level category 2, drums and similar) and idiophones (high-level category 1, cymbals, bells, xylophone-like instruments and similar). A few instruments that are sometimes considered percussion are classified as chordophones (high-level category 3, such as the hammered dulcimer) and as aerophones (high-level category 4, such as the samba whistle). Conversely, the members of the Hornbostel–Sachs high-level categories 1 and 2 nearly all fall clearly or loosely into the conventional category of percussion.
Hornbostel–Sachs does use the term percussion to divide the third-level category directly struck idiophones (111) into percussion idiophones (111.2), those beaten with a hand or beater, such as a suspended cymbal, and concussion idiophones (111.1), those beaten together in pairs such as clash cymbals. The term is also used in a loosely related way to divide reed aerophones (422) into single reed instruments (422.2) with a single 'reed' consisting of a percussion lamella (our emphasis) and double reeds (422.1) also called concussion reeds.
Several older systems divide instruments into two high-level classes:
This system was developed by André Schaeffner into a comprehensive classification scheme in 1932. [4]
Percussion is traditionally divided into pitched percussion, which produces a sensation of pitch, and unpitched percussion, which does not. Some instruments, such as bells, are commonly used in both roles.
The traditional terms tuned percussion and untuned percussion have fallen from favour, replaced loosely by the terms pitched and unpitched, see Unpitched percussion instrument#Untuned percussion.

By far the most common way of classifying percussion is by the style or tradition with which it is most closely associated.
An orchestral percussion section is traditionally divided into:
Keyboard instruments such as the celesta are not normally part of the percussion section, as the playing skills required are significantly different.
Some percussion instruments may be classified according to the material of which they, or their sounding component, are constructed. In this way some idiophones for example are sometimes grouped together as metallophones and others as lithophones.
This scheme does not have any wider acceptance, to the point that some terms that might be used in such schemes have meanings in general usage that are inconsistent with it. For example, the serpent is a brass instrument although composed of wood, while many gongs and some cymbals are composed of brass but are not brass instruments, and the modern orchestral flute is a woodwind instrument although composed of silver and/or other metals.
A percussion instrument is a musical instrument that is sounded by being struck or scraped by a beater including attached or enclosed beaters or rattles struck, scraped or rubbed by hand or struck against another similar instrument. Excluding zoomusicological instruments and the human voice, the percussion family is believed to include the oldest musical instruments. In spite of being a very common term to designate instruments, and to relate them to their players, the percussionists, percussion is not a systematic classificatory category of instruments, as described by the scientific field of organology. It is shown below that percussion instruments may belong to the organological classes of ideophone, membranophone, aerophone and cordophone.
In organology, the study of musical instruments, many methods of classifying instruments exist. Most methods are specific to a particular cultural group and were developed to serve that culture's musical needs. Culture-based classification methods sometimes break down when applied outside that culture. For example, a classification based on instrument use may fail when applied to another culture that uses the same instrument differently.
Hornbostel–Sachs or Sachs–Hornbostel is a system of musical instrument classification devised by Erich Moritz von Hornbostel and Curt Sachs, and first published in the Zeitschrift für Ethnologie in 1914. An English translation was published in the Galpin Society Journal in 1961. It is the most widely used system for classifying musical instruments by ethnomusicologists and organologists. The system was updated in 2011 as part of the work of the Musical Instrument Museums Online (MIMO) Project.
A membranophone is any musical instrument which produces sound primarily by way of a vibrating stretched membrane. It is one of the four main divisions of instruments in the original Hornbostel-Sachs scheme of musical instrument classification.
An idiophone is any musical instrument that creates sound primarily by the vibration of the instrument itself, without the use of air flow, strings (chordophones), membranes (membranophones) or electricity (electrophones). It is the first of the four main divisions in the original Hornbostel–Sachs system of musical instrument classification. The early classification of Victor-Charles Mahillon called this group of instruments autophones. The most common are struck idiophones, or concussion idiophones, which are made to vibrate by being struck, either directly with a stick or hand or indirectly, with scraping or shaking motions. Various types of bells fall into both categories. A common plucked idiophone is the Jew's harp.
Organology is the science of musical instruments and their classifications. It embraces study of instruments' history, instruments used in different cultures, technical aspects of how instruments produce sound, and musical instrument classification. There is a degree of overlap between organology, ethnomusicology and the branch of the science of acoustics devoted to musical instruments.
A lamellophone is a member of the family of musical instruments that makes its sound by a thin vibrating plate called a lamella or tongue, which is fixed at one end and has the other end free. When the musician depresses the free end of a plate with a finger or fingernail, and then allows the finger to slip off, the released plate vibrates. An instrument may have a single tongue or a series of multiple tongues.
A rattle is a type of percussion instrument which produces a sound when shaken. Rattles are described in the Hornbostel–Sachs system as Shaken Idiophones or Rattles (112.1).
Percussion may refer to:
Struck idiophones is one of the categories of idiophones that are found in the Hornbostel-Sachs system of musical instrument classification.
A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies.
A pitched percussion instrument is a percussion instrument used to produce musical notes of one or more pitches, as opposed to an unpitched percussion instrument which is used to produce sounds of indefinite pitch.
