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.
According to Sachs,
The sound is produced by a membrane ["skin" or "head"] stretched over an opening. Most, but not all, membranophones are generally called drums. They are classified according to material, if it's single or double headed, shape, skin(s), skin fastening, playing positions, and manner of playing. [1]
The Hornbostel-Sachs scheme of musical instrument classification divides membranophones in a numeric taxonomy based on how the sound is produced:
Membranophones can also be divided into small divisions based on length and breadth of sound production: [3]
SIL International maintains a classification system based largely on shape: [5]
The traditional classification of Indian instruments include two categories of percussion. [6]
The predrum category consists of simple drum-like percussion instruments. These include the ground drum, which, in its most common §—Form, consists of an animal skin stretched over a hole in the ground, and the pot drum, made from a simple pot. [7]
Water drums are also sometimes treated as a distinct category of membranophone. Common in Native American music and the music of Africa, water drums are characterized by a unique sound caused by filling the drum with some amount of water. [8]
The talking drum is an important category of West African membranophone, characterized by the use of varying tones to "talk". Talking drums are used to communicate across distances. [9]
Military drums or war drums are drums in various forms that have been used in the military.
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 idiophone, membranophone, aerophone and chordophone.
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.
An aerophone is a musical instrument that 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.
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–Sach 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.
The eunuch flute, onion flute, or mirliton is a membranophone used during the 16th and 17th centuries. It produces music akin to a comb and paper, and is still manufactured as a toy.
A damaru is a small two-headed drum, used in Hinduism and Tibetan Buddhism. In Hinduism, the damaru is known as the instrument of the deity Shiva, associated with Tantric traditions. It is said to be created by Shiva to produce spiritual sounds by which the whole universe has been created and regulated. In Tibetan Buddhism, the damaru is used as an instrument in meditation practices.
A family of musical instruments is a grouping of several different but related sizes or types of instruments. Some schemes of musical instrument classification, such as the Hornbostel-Sachs system, are based on a hierarchy of instrument families and families of families.
Directly struck membranophones is one of the sub-categories of musical instruments found in the Hornbostel-Sachs system of musical instrument classification. The type of membranophones or drums found in this group are those instruments that produce sound when struck directly by the performer. The membrane of these drums is hit with a stick, the hand, or something else. Drums that produce sound by means of plucking an attached string or by means of friction are grouped in a different category.
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.
There are several overlapping schemes for the classification of percussion instruments.
The conservation and restoration of musical instruments is performed by conservator-restorers who are professionals, properly trained to preserve or protect historical and current musical instruments from past or future damage or deterioration. Because musical instruments can be made entirely of, or simply contain, a wide variety of materials such as plastics, woods, metals, silks, and skin, to name a few, a conservator should be well-trained in how to properly examine the many types of construction materials used in order to provide the highest level or preventive and restorative conservation.
