Musical instrument classification in the context of "Stringed musical instrument"

In musical instrument classification, string instruments, or chordophones, are musical instruments that produce sound from vibrating strings when a performer strums, plucks, strikes or sounds the strings in varying manners.

Musicians play some string instruments, like guitars, by plucking the strings with their fingers or a plectrum (pick), and others by hitting the strings with a light wooden hammer or by rubbing the strings with a bow, like violins. In some keyboard instruments, such as the harpsichord, the musician presses a key that plucks the string. Other musical instruments generate sound by striking the string.

Hornbostel–Sachs or Sachs–Hornbostel is a system of musical instrument classification devised by Erich Moritz von Hornbostel and Curt Sachs. This system was first published in the Zeitschrift für Ethnologie in 1914. An English translation was published in the Galpin Society Journal in 1961, which is the most widely used system for classifying musical instruments by ethnomusicologists and organologists (people who study musical instruments). The system was updated in 2011 as part of the work of the Musical Instrument Museums Online (MIMO) Project.

Hornbostel and Sachs based their ideas on a system devised in the late 19th century by Victor-Charles Mahillon, the curator of musical instruments at Brussels Conservatory. Mahillon divided instruments into four broad categories according to the nature of the sound-producing material: an air column; string; membrane; and body of the instrument. From this basis, Hornbostel and Sachs expanded Mahillon's system to make it possible to classify any instrument from any culture.

Organology (/ˌɔːrɡəˈnɒlədʒi/; from Ancient Greek ὄργανον organon 'instrument' and λόγος logos 'the study of') 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 (being subsets of musicology) and the branch of the science of acoustics devoted to musical instruments.

A folk instrument is a traditional musical instrument that has remained largely restricted to traditional folk music, and is not usually used in the classical music or other elite and formal musical genres of the culture concerned, though related instruments may be.

It can be made from wood, metal or other material; all the major families of instruments are represented. The instruments can be percussion instruments, or different types of flutes or trumpets, or string instruments that are plucked, hammered or use a form of bow.

Erich Moritz von Hornbostel (25 February 1877 – 28 November 1935) was an Austrian ethnomusicologist, comparative musicologist, and scholar of music. He is remembered for his pioneering work in the field of ethnomusicology, and for the Sachs–Hornbostel system of musical instrument classification which he co-authored with Curt Sachs. He is also known as the father of the "Berlin School of Ethnomusicology" in conjunction with Carl Stumpf.

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. Orchestral instruments are classified as families based on their commonalities.
