Sympathetic 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 desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonic
A harmonic is a wave with a frequency that is a positive integer multiple of the ''fundamental frequency'', the frequency of the original periodic signal, such as a sinusoidal wave. The original signal 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 wind instrum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timbre
In music, timbre ( ), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or musical tone, tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments. It also enables listeners to distinguish different instruments in the same category (e.g., an oboe and a clarinet, both Woodwind instrument, woodwind instruments). In simple terms, timbre is what makes a particular musical instrument or human voice have a different sound from another, even when they play or sing the same note. For instance, it is the difference in sound between a guitar and a piano playing the same note at the same volume. Both instruments can sound equally tuned in relation to each other as they play the same note, and while playing at the same amplitude level each instrument will still sound distinctively with its own unique tone color. Experienced musicians are able to distinguish between diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge (instrument)
A bridge is a device that supports the strings on a stringed musical instrument and transmits the vibration of those strings to another structural component of the instrument—typically a 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 displace only a small volume of air as they vibrate. Consequently, the sound of the strings alone requires impedance matching to the surrounding air by transmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 pegs or mechanism that holds the strings at the "head" of the instrument. 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, consequentially, 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 Steinberger guitar or some Chapman stick models. The headst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Guitar
An electric guitar is a guitar that requires external amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar (however combinations of the two - a semi-acoustic guitar and an electric acoustic guitar exist). It uses one or more pickups to convert the vibration of its strings into 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 on the amplifier settings or the knobs on the guitar from that of an acoustic guitar. Often, this is done through the use of effects such as reverb, distortion and "overdrive"; the latter is considered to be a key element of electric blues guitar music and jazz and rock guitar playing. Invented in 1932, the electric guitar was adopted by jazz guitar players, who wanted to play single-note guitar solos in large big band ensembles. Early proponents of the electric guitar on ...

Aliquot Stringing
Aliquot stringing is the use of extra, un-struck strings in the 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) stri ...

Pianos
The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. It was invented in Italy by Bartolomeo Cristofori around the year 1700. Description The word "piano" is a shortened form of ''pianoforte'', the Italian term for the early 1700s versions of the instrument, which in turn derives from ''clavicembalo col piano e forte'' (key cimbalom with quiet and loud)Pollens (1995, 238) and ''fortepiano''. The Italian musical terms ''piano'' and ''forte'' indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the grea ...

Hurdy-gurdy
The hurdy-gurdy is a string instrument that produces sound by a hand-crank-turned, rosined wheel rubbing against the strings. The wheel functions much like a violin bow, and single notes played on the instrument sound similar to those of a violin. Melodies are played on a keyboard that presses ''tangents''—small wedges, typically made of wood—against one or more of the strings to change their pitch. Like most other acoustic stringed instruments, it has a sound board and hollow cavity to make the vibration of the strings audible. Most hurdy-gurdies have multiple 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, Aragonese, Cajun French, Asturian, Cantabrian, Galician, Hungarian, and Slavic folk music. One or more of the drone strings usually passes over a loose bridge that can be made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viola D'amore
The viola d'amore (; Italian for "viol of love") is a 7- or 6- stringed musical instrument with 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 on ...

Sitar
The sitar ( or ; ) is a plucked stringed instrument, originating from the Indian subcontinent, used in Hindustani classical music. The instrument was invented in medieval India, flourished in the 18th century, and arrived at its present form in 19th-century India. Khusrau Khan, an 18th century figure of Mughal Empire has been identified by modern scholarship as the originator of Sitar. According to most historians he developed sitar from setar, an Iranian instrument of Abbasid or Safavid origin. Another view supported by a minority of scholars is that Khusrau Khan developed it from ''Veena''. 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. In the 1960s, a short-lived trend arose for the use of the sitar in Western popular music, with the instrument appearing on tracks by bands such as the Beatles, the Doors, the Rolling Stones and 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. In Western ...

Tremolo Arm
A vibrato system on a guitar is a mechanical device used to temporarily change the pitch of the strings. Instruments without a vibrato have other bridge and tailpiece systems. They add vibrato to the sound by changing the tension of the strings, typically at the bridge or tailpiece of an electric guitar using a controlling lever, which is alternately referred to as a whammy bar, vibrato bar, or incorrectly as a tremolo arm. The lever enables the player to quickly and temporarily vary the tension and sometimes length of the strings, changing the pitch to create a vibrato, portamento, or pitch bend effect. The pitch-bending effects have become an important part of many styles, allowing creation of sounds that could not be played without the device, such as the 1980s-era shred guitar " dive bomb" effect. The mechanical vibrato systems began as a device for more easily producing the vibrato effects that blues and jazz guitarists had achieved on arch top guitars by manipulating the ...
