The guitar is a stringed musical instrument, that is usually fretted and typically has six or twelve strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A guitar pick may also be used to strike the strings. The sound of the guitar is projected either acoustically, by means of a resonant hollow chamber on the guitar, or amplified by an electronic pickup and an amplifier.
In musical instrument classification, string instruments or chordophones, are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
Mbira are a family of musical instruments, traditional to the Shona people of Zimbabwe. They consist of a wooden board with attached staggered metal tines, played by holding the instrument in the hands and plucking the tines with the thumbs, the right forefinger, and sometimes the left forefinger. Musicologists classify it as a lamellaphone, part of the plucked idiophone family of musical instruments. In Eastern and Southern Africa, there are many kinds of mbira, often accompanied by the hosho, a percussion instrument. It is often an important instrument played at religious ceremonies, weddings, and other social gatherings. The "Art of crafting and playing Mbira/Sansi, the finger-plucking traditional musical instrument in Malawi and Zimbabwe" was added to the UNESCO Representative List of the Intangible Cultural Heritage of Humanity in 2020.
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 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.
An electric piano is a musical instrument that has a piano-style musical keyboard, where sound is produced by means of mechanical hammers striking metal strings or reeds or wire tines, which leads to vibrations which are then converted into electrical signals by pickups. The pickups are connected to an instrument amplifier and loudspeaker to reinforce the sound sufficiently for the performer and audience to hear. Unlike a synthesizer, the electric piano is not an electronic instrument. Instead, it is an electro-mechanical instrument. Some early electric pianos used lengths of wire to produce the tone, like a traditional piano. Smaller electric pianos used short slivers of steel to produce the tone. The earliest electric pianos were invented in the late 1920s; the 1929 Neo-Bechstein electric grand piano was among the first. Probably the earliest stringless model was Lloyd Loar's Vivi-Tone Clavier. A few other noteworthy producers of electric pianos include Baldwin Piano and Organ Company, and the Wurlitzer Company.
The marímbula is a plucked box musical instrument of the Caribbean. In Cuba it is common in the changüí genre, as well as old styles of son. In Mexico, where it is known as marimbol is played in son jarocho; in the Dominican Republic, where it is known as marimba, it is played in merengue típico, and in Jamaica it is known as rumba box and played in mento.
The morsing is an instrument similar to the Jew's harp, mainly used in Rajasthan, in the Carnatic music of South India, and in Sindh, Pakistan. It can be categorized under lamellophones, which is a sub-category of plucked idiophones. The instrument consists of a metal ring in the shape of a horseshoe with two parallel forks which form the frame, and a metal tongue in the middle, between the forks, fixed to the ring at one end and free to vibrate at the other. The metal tongue, also called the trigger, is bent at the free end in a plane perpendicular to the circular ring so that it can be struck and made to vibrate.
The Gravikord is a 24 string electric double bridge-harp invented by Robert Grawi in 1984, which is closely related to both the West African kora and the mbira. It was designed to employ a separated double tonal array structure making it possible to easily play cross-rhythms in a polyrhythmic musical style in a modern electro-acoustic instrument. The Gravi-kora is a similar instrument, also developed by Grawi, which is tuned identically to a traditional 21 string kora.
Struck idiophones is one of the categories of idiophones that are found in the Hornbostel-Sachs system of musical instrument classification.
An acoustic guitar is a musical instrument in the string family. When a string is plucked, its vibration is transmitted from the bridge, resonating throughout the top of the guitar. It is also transmitted to the side and back of the instrument, resonating through the air in the body, and producing sound from the sound hole. While the original, general term for this stringed instrument is guitar, the retronym 'acoustic guitar' – often used to indicate the steel stringed model – distinguishes it from an electric guitar, which relies on electronic amplification. Typically, a guitar's body is a sound box, of which the top side serves as a sound board that enhances the vibration sounds of the strings. In standard tuning the guitar's six strings are tuned (low to high) E2 A2 D3 G3 B3 E4.
The agidigbo or ‘’’molo’’’ is a large traditional plucked lamellophone thumb piano used by the Yoruba people of Nigeria to play apala music.
The Array mbira is a handcrafted modern musical instrument with a unique harp- or bell-like sound. It is made in the United States by its inventor Bill Wesley and manufactured by Wesley with Patrick Hadley in San Diego, California, United States. Its development began in the 1960s. It is a radical redesign of the Shona African mbira from Zimbabwe and is part of the lamellaphone family.
Reed aerophones is one of the categories of musical instruments found in the Hornbostel-Sachs system of musical instrument classification. In order to produce sound with these Aerophones the player's breath is directed against a lamella or pair of lamellae which periodically interrupt the airflow and cause the air to be set in motion.
The Guitaret is an electric lamellophone made by Hohner and invented by Ernst Zacharias, in 1963. Zacharias also invented similar instruments like the Pianet, Cembalet and the Clavinet.
A marimba is a xylophone-like percussion instrument played with mallets.
There are several overlapping schemes for the classification of percussion instruments.
