The cello ( CHEL-oh), or violoncello ( VY-ə-lən-CHEL-oh, Italian pronunciation:[vjolonˈtʃɛllo]), is a bowed (sometimes plucked and occasionally hit) string instrument of the violin family. Its four strings are usually tuned in perfect fifths: from low to high, C2, G2, D3 and A3. The viola's four strings are each an octave higher. Music for the cello is generally written in the bass clef, with tenor clef, and treble clef used for higher-range passages.
The double bass, also known as the upright bass for distinguishing purposes, or simply as the bass, is the largest and lowest-pitched chordophone, in the modern symphony orchestra. Similar in structure to the cello, it has four or five strings.
The violin, colloquially known as a fiddle, is a wooden chordophone, and is the smallest, and thus highest-pitched instrument (soprano) in regular use in the violin family. Smaller violin-type instruments exist, including the violino piccolo and the pochette, but these are virtually unused. Most violins have a hollow wooden body, and commonly have four strings, usually tuned in perfect fifths with notes G3, D4, A4, E5, and are most commonly played by drawing a bow across the strings. The violin can also be played by plucking the strings with the fingers (pizzicato) and, in specialized cases, by striking the strings with the wooden side of the bow.
In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal. The fundamental frequency is also called the 1st harmonic; the other harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. The set of harmonics forms a harmonic series.
An overtone is any resonant frequency above the fundamental frequency of a sound. In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave. The relative volume or amplitude of various overtone partials is one of the key identifying features of timbre, or the individual characteristic of a sound.
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.
Pizzicato is a playing technique that involves plucking the strings of a string instrument. The exact technique varies somewhat depending on the type of instrument:
A pull-off is a stringed instrument playing and articulation technique performed by plucking or "pulling" the finger that is grasping the sounding part of a string off the fingerboard of either a fretted or unfretted instrument. This intermediate- to advanced playing technique is done using the tip of a finger or fingernail on the fretting hand. Pull-offs are done to facilitate the playing of embellishments and ornaments such as grace notes. Pull-offs may be notated in sheet music or improvised by the performer, depending on the musical style and context.
In music, inharmonicity is the degree to which the frequencies of overtones depart from whole multiples of the fundamental frequency.
A prepared guitar is a guitar that has had its timbre altered by placing various objects on or between the instrument's strings, including other extended techniques. This practice is sometimes called tabletop guitar, because many prepared guitarists do not hold the instrument in the usual manner, but instead place the guitar on a table to manipulate it.
A multiphonic is an extended technique on a monophonic musical instrument in which several notes are produced at once. This includes wind, reed, and brass instruments, as well as the human voice. Multiphonic-like sounds on string instruments, both bowed and hammered, have also been called multiphonics, for lack of better terminology and scarcity of research.
The electric upright bass (EUB) is an instrument that can perform the musical function of a double bass. It requires only a minimal or 'skeleton' body to produce sound because it uses a pickup and electronic amplifier and loudspeaker. Therefore, a large resonating structure is not required to project the sound into the air. This minimal body greatly reduces the bulk and weight of the instrument. EUBs must always be connected to an amplifier and speaker cabinet to produce an adequate audible sound. The EUB retains enough of the features of the double bass so that double bass players are able to perform on it.
Playing the violin entails holding the instrument between the jaw and the collar bone. The strings are sounded either by drawing the bow across them (arco), or by plucking them (pizzicato). The left hand regulates the sounding length of the strings by stopping them against the fingerboard with the fingers, producing different pitches.
An experimental musical instrument is a musical instrument that modifies or extends an existing instrument or class of instruments, or defines or creates a new class of instrument. Some are created through simple modifications, such as cracked cymbals or metal objects inserted between piano strings in a prepared piano. Some experimental instruments are created from household items like a homemade mute for brass instruments such as bathtub plugs. Other experimental instruments are created from electronic spare parts, or by mixing acoustic instruments with electric components.
String instruments are capable of producing a variety of extended technique sounds. These alternative playing techniques have been used extensively since the 20th century. Particularly famous examples of string instrument extended technique can be found in the music of Krzysztof Penderecki, Witold Lutosławski, George Crumb, and Helmut Lachenmann.
The 3rd bridge is an extended playing technique used on the electric guitar and other string instruments that allows a musician to produce distinctive timbres and overtones that are unavailable on a conventional string instrument with two bridges. The timbre created with this technique is close to that of gamelan instruments like the bonang and similar Indonesian types of pitched gongs.
A third bridge can be devised by inserting a rigid preparation object between the strings and the body or neck of the instrument, effectively dividing the string into distinct vibrating segments.
Guitar picking is a group of hand and finger techniques a guitarist uses to set guitar strings in motion to produce audible notes. These techniques involve plucking, strumming, brushing, etc. Picking can be done with:
Piano extended techniques are those in which unorthodox or unconventional techniques are used to create the sound.
Playing the cello is done while seated with the instrument supported on the floor. The fingertips of the left hand stop the strings on the fingerboard to determine the pitch of the fingered note. The right hand plucks or bows the strings to sound the notes.
The American composer Harry Partch (1901-1974) composed using scales of unequal intervals in just intonation, derived from the natural Harmonic series; these scales allowed for more tones of smaller intervals than in the standard Western tuning, which uses twelve equal intervals. The tonal system Partch used has 43 tones to the octave. To play this music he invented and built many new instruments, with names such as the Chromelodeon, the Quadrangularis Reversum, and the Zymo-Xyl.
