String Resonance
Sympathetic resonance or sympathetic vibration is a harmonic phenomenon wherein a passive string or vibratory body responds to external vibrations to which it has a harmonic likeness. The classic example is demonstrated with two similarly-tuned tuning forks. When one fork is struck and held near the other, vibrations are induced in the unstruck fork, even though there is no physical contact between them. In similar fashion, strings will respond to the vibrations of a tuning fork when sufficient harmonic relations exist between them. The effect is most noticeable when the two bodies are tuned in unison or an octave apart (corresponding to the first and second harmonics, integer multiples of the inducing frequency), as there is the greatest similarity in vibrational frequency. Sympathetic resonance is an example of injection locking occurring between coupled oscillators, in this case coupled through vibrating air. In musical instruments, sympathetic resonance can produce both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonic
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''. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields. For example, if the fundamental frequency is 50 Hz, a common AC power supply frequency, the frequencies of the first three higher harmonics are 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 200 Hz (4th harmonic) and any addition of waves with these frequencies is periodic at 50 Hz. In music, harmonics are used on string instruments and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overtone
An overtone is any resonant frequency above the fundamental frequency of a sound. (An overtone may or may not be a harmonic) 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. Using the model of Fourier analysis, the fundamental and the overtones together are called Harmonic series (music)#Partial, partials. Harmonics, or more precisely, harmonic partials, are partials whose frequencies are numerical integer multiples of the fundamental (including the fundamental, which is 1 times itself). These overlapping terms are variously used when discussing the acoustic behavior of musical instruments.Alexander John Ellis, A ...

Bridge (instrument)
A bridge is a device that supports the strings (music), strings on a stringed instrument, stringed musical instrument and transmits the vibration of those strings to another structural component of the instrument—typically a Sound board (music), soundboard, such as the top of a guitar or violin—which transfers the sound to the surrounding air. Depending on the instrument, the bridge may be made of carved wood (violin family instruments, acoustic guitars and some jazz guitars), metal (electric guitars such as the Fender Telecaster) or other materials. The bridge supports the strings and holds them over the body of the instrument under tension. Explanation Most stringed instruments produce sound through the application of energy to the strings, which sets them into vibratory motion, creating musical sounds. The strings alone, however, produce only a faint sound because they Particle displacement, displace only a small volume of air as they vibrate. Consequently, the sound of ...

String Tree (instrument)
A headstock or peghead is part of a guitar or similar stringed instruments such as a lute, mandolin, banjo, ukulele and others of the lute lineage. The main function of a headstock is to house the tuning pegs or other mechanism that holds the strings at the "head" of the instrument; it corresponds to a pegbox in the violin family. At the "tail" of the instrument the strings are usually held by a tailpiece or bridge. Machine heads on the headstock are commonly used to tune the instrument by adjusting the tension of strings and, consequently, the pitch of sound they produce. Construction details Two traditional layouts of guitar tuners are called "3+3" (3 top tuners and 3 bottom ones) and "6 in line" tuners, though many other combinations are known, especially for bass guitars and non-6-string guitars. When there are no machine heads (i.e. tuners are not needed or located in some other place, for example, on guitar body), the guitar headstock may be missing completely, as in ...

Electric Guitar
An electric guitar is a guitar that requires external electric Guitar amplifier, sound amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar. It uses one or more pickup (music technology), pickups to convert the vibration of its strings into Electrical signal, electrical signals, which ultimately are reproduced as sound by loudspeakers. The sound is sometimes shaped or electronically altered to achieve different timbres or tonal qualities via amplifier settings or knobs on the guitar. Often, this is done through the use of Effects unit, effects such as reverb, Distortion (music), distortion and "overdrive"; the latter is considered to be a key element of electric blues guitar music and jazz, rock music, rock and Heavy metal music, heavy metal guitar playing. Designs also exist combining attributes of electric and acoustic guitars: the Semi-acoustic guitar, semi-acoustic and Acoustic-electric guitar, acoustic-electric guitars. Inven ...

Aliquot Stringing
Aliquot stringing is the use of extra, un-struck strings in a piano for the purpose of enriching the tone. Aliquot systems use an additional (hence fourth) string in each note of the top three piano octaves. This string is positioned slightly above the other three strings so that it is not struck by the hammer. Whenever the hammer strikes the three conventional strings, the aliquot string vibrates sympathetically. Aliquot stringing broadens the vibrational energy throughout the instrument, and creates an unusually complex and colorful tone. Etymology The word ''aliquot'' ultimately comes from a Latin word meaning 'some, several'. In mathematics, ''aliquot'' means 'an exact part or divisor', reflecting the fact that the length of an aliquot string forms an exact division of the length of longer strings with which it vibrates sympathetically. History Julius Blüthner invented the aliquot stringing system in 1873. The Blüthner aliquot system uses an additional (hence fourth) s ...

Pianos
A piano is a keyboard instrument that produces sound when its keys are depressed, activating an action mechanism where hammers strike strings. Modern pianos have a row of 88 black and white keys, tuned to a chromatic scale in equal temperament. A musician who specializes in piano is called a pianist. There are two main types of piano: the grand piano and the upright piano. The grand piano offers better sound and more precise key control, making it the preferred choice when space and budget allow. The grand piano is also considered a necessity in venues hosting skilled pianists. The upright piano is more commonly used because of its smaller size and lower cost. When a key is depressed, the strings inside are struck by felt-coated wooden hammers. The vibrations are transmitted through a bridge to a soundboard that amplifies the sound by coupling the acoustic energy to the air. When the key is released, a damper stops the string's vibration, ending the sound. Most notes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardanger Fiddle
A hardanger fiddle () is a traditional stringed instrument considered the national instrument of Norway. In modern designs, this type of fiddle is very similar to the violin, though with eight or nine strings (rather than four as on a standard violin) and thinner wood. The earliest known example of the is from 1651, made by Ole Jonsen Jaastad in Hardanger, Norway. Originally, the instrument had a rounder, narrower body. Around the year 1850, the modern layout with a body much like the violin became the norm. The F-holes of the hardanger fiddle are distinctive, oftentimes with a more "sunken" appearance, and generally straighter edges (unlike the frilly, swirly F-holes of a violin). Four of the strings are strung and played like a violin, while the rest, named understrings or sympathetic strings, resonate under the influence of the other four. These additional strings are tuned and secured with extra pegs at the top of the scroll, effectively doubling the length of a Hardingf ...

Hurdy-gurdy
The hurdy-gurdy is a string instrument that produces sound by a hand-turned crank, rosined wheel rubbing against the strings. The wheel functions much like a violin (or nyckelharpa) bow, and single notes played on the instrument sound similar to those of a violin. Melodies are played on a musical keyboard, keyboard that presses ''tangents''—small wedges, typically made of wood or metal—against one or more of the strings to change their pitch. Like most other acoustic stringed instruments, it has a sound board (music), sound board and hollow cavity to make the vibration of the strings audible. Most hurdy-gurdies have multiple drone (music), drone strings, which give a constant pitch accompaniment to the melody, resulting in a sound similar to that of bagpipes. For this reason, the hurdy-gurdy is often used interchangeably or along with bagpipes. It is mostly used in Occitan folk music, Occitan, Music of Aragon, Aragonese, Cajun music, Cajun French, Music of Galicia, Cantabri ...

Viola D'amore
The viola d'amore (; ) is a 7- or 6- stringed musical instrument with additional sympathetic strings used chiefly in the baroque period. It is played under the chin in the same manner as the violin. Structure and sound The viola d'amore shares many features of the viol family. It looks like a thinner treble viol without frets and sometimes with sympathetic strings added. The six-string viola d'amore and the treble viol also have approximately the same ambitus or range of playable notes. Like all viols, it has a flat back. An intricately carved head at the top of the peg box is common on both viols and viola d'amore, although some viols lack one. Unlike the carved heads on viols, the viola d'amore's head occurs most often as Cupid blindfolded to represent the blindness of love. Its sound-holes are commonly in the shape of a flaming sword known as "The Flaming Sword of Islam" (suggesting the instrument's development was influenced by the Islamic World). This was one of the thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sitar
The sitar ( or ; ) is a plucked stringed instrument, originating from the Indian subcontinent, used in Hindustani classical music. The instrument was invented in the 18th century, and arrived at its present form in 19th-century India. Khusrau Khan, an 18th-century figure of the Mughal Empire has been identified by modern scholarship as the inventor of the sitar. According to most historians, he developed the sitar from the setar, an Iranian instrument of Abbasid or Safavid origin. Used widely throughout the Indian subcontinent, the sitar became popularly known in the wider world through the works of Ravi Shankar, beginning in the late 1950s and early 1960s. The advent of Psychedelia, psychedelic culture during the mid-to-late 1960s set a trend for the use of the sitar in popular music, sitar in Western popular music, with the instrument appearing on tracks by bands such as the Beatles, the Rolling Stones, Metallica and many others.

Sympathetic String
Sympathetic strings or resonance strings are auxiliary strings found on many Indian musical instruments, as well as some Western Baroque instruments and a variety of folk instruments. They are typically not played directly by the performer (except occasionally as an effect), only indirectly through the tones that are played on the main strings, based on the principle of sympathetic resonance. The resonance is most often heard when the fundamental frequency of the string is in unison or an octave lower or higher than the catalyst note, although it can occur for other intervals, such as a fifth, with less effect. Description Sympathetic strings are used to enhance the sound of an instrument. Some instruments have only a few sympathetic strings such as the Hardanger fiddle (pictured above right). Other instruments which have more include the sitar with 11-13 sympathetic strings and sarod with 15 sympathetic strings, and the sarangi, which has a total of 37 sympathetics. ...
