The strings are the largest family of instruments in the orchestra and they come in four sizes: the violin, which is the smallest, viola, cello, and the biggest, the double bass, sometimes called the contrabass. (Bass is pronounced "base," as in "baseball.")

- The production of sound
stringed instrument, any musical instrument that produces sound by the vibration of stretched strings, which may be made of vegetable fibre, metal, animal gut, silk, or artificial materials such as plastic or nylon. In nearly all stringed instruments the sound of the vibrating string is amplified by the use of a resonating chamber or soundboard. The string may be struck, plucked, rubbed (bowed), or, occasionally, blown (by the wind); in each case the effect is to displace the string from its normal position of rest and to cause it to vibrate in complex patterns.
Because most stringed instruments are made from wood or other easily perishable materials, their history before written documentation is almost unknown, and contemporary knowledge of “early” instruments is limited to the ancient cultures of East Asia and South Asia, the Mediterranean, Egypt, and Mesopotamia; but even for these places historians must depend largely on iconographic (pictorial) sources rather than surviving specimens.
Stringed instruments seem to have spread rapidly from one society to another across the length and breadth of Eurasia by means of great population shifts, invasions and counterinvasions, trade, and, presumably, sheer cultural curiosity. In the Middle Ages the Crusades (late 11th through the late 13th century) stimulated Europe to adopt a whole set of new instruments; similarly, the Chinese adopted many new instruments from their Central Asian neighbours as Buddhism spread eastward and as the Han Chinese expanded their influence across the region (roughly, the 3rd century bce to the 10th century ce). Indeed, the only world area that did not echo to the sound of strings was the pre-Columbian Americas.
No system of classification can adequately categorize the interactions of natural material, craftsmanship, and exuberant imagination that produced an endless variety of stringed instruments. In the West the most widely accepted system of classification is that developed by E.M. von Hornbostel and Curt Sachs, a method based on the type of material that is set into vibration to produce the original sound. Thus, stringed instruments are identified as chordophones—that is to say, instruments in which the sound is produced by the vibration of chords, or strings. This main category is then further divided into four subtypes—lutes, zithers, lyres, and harps—according to the manner in which the strings are positioned in relation to the body of the instrument. Within these categories, the descriptive nomenclature of an instrument is given in terms of parts of the body: for example, the belly (front; soundboard), back, sides, and neck. Instruments are not necessarily related only to others in the same classification. Transformations continually occur, and “hybrids,” according to the Sachs-Hornbostel system, may in fact represent altogether viable subtypes of their own.

Musical Instruments
The ear, because of its own structure, adds to and subtracts from the outside sound. It is, for instance, relatively insensitive to low-frequency sound pressure but is extremely sensitive to fine degrees of pitch change. At the same time, it can accept a great number of pitch and tuning systems. On a worldwide basis, there are a large and varied number of tonal systems, the most ancient stemming from China. The oldest known of these in the West is the so-called Pythagorean system, articulated by the famed 7th-century Greek philosopher and mathematician Pythagoras; others include meantone temperament, just intonation, and the equal-tempered system, methods of tuning calculation that vary slightly in the exact size they assign to the intervals within an octave. All of these systems represent theoretical mathematical concepts to some degree, and their origins must be sought in arcane numerological systems rather than in practical musicianship. Thus, “tuning” and “playing in tune” do not necessarily refer to the same thing; players and tuners make constant adjustments to any basic mathematically determined framework according to their judgment and experience. In other words, even though a given “scientific” tuning system outlines scales and modes, the instrumentalist who plays an instrument with great pitch flexibility (the violin, for instance) spends much time in the spaces between the notes assigned in the given scale. The Japanese zither (koto), for example, can be tuned according to a number of fixed systems; nevertheless, its player produces many microtonal (using intervals that differ from the equally spaced semitones of Western music) variations on these fixed pitches by manipulation of the strings. The person who plays the Vietnamese dan bau monochord creates all pitches and nuances on its metal string by pulling in the flexible bamboo stem to which it is attached. In Western musical tradition, moreover, piano tuners would not think of tuning altogether according to the dictates of a well-tempered system; rather, they use a so-called stretched tuning, in which they imperceptibly sharpen (raise) pitches as they ascend and thus make the highest notes relatively sharper than the lowest ones. Investigation has disclosed that string players tend to play in the Pythagorean rather than the well-tempered system.
Inconsistencies, then, are inherent in all tuning systems; makers of fretted lutes—such as the guitar and the Greek laouto (a type of lute with moveable frets), for example—operate according to a combination of ear and rule of thumb when they insert or adjust frets (note-position markers—e.g., of gut or wire) in the fingerboard. Such instruments are fretted according to the “rule of the eighteenth,” in which the first fret is placed at one-eighteenth of the distance from the top to the bottom of the string, the second, one-eighteenth of the distance from the first fret to the bottom, and so on. Even if this method produced an acoustically perfect scale (which it does not), the player would not be able to reproduce this exactly, for as he presses the string to the fingerboard, the string is stretched and is thus slightly lengthened. That is why the act of stopping a string at its exact centre gives a note slightly sharper than the expected octave above the open string. Despite all of this, the search for an acoustically perfect tuning system goes on.

Though constructional methods differ widely from one area and instrument to another, there are a limited number of basic problems to be overcome by the maker of stringed instruments. The very principle that makes it possible for chordophones to sound is string tension; at the same time, tension is destructive to the instrument, since it tends literally to pull it apart. So the body of an instrument must be made of strong material; it must be reinforced, and, at the same time, it must not be so rigid that it cannot easily resonate—i.e., produce a supplementary vibration intensifying that of the string. The challenge of reconciling these opposite needs is the central one for the chordophone maker. Climate too has a marked effect on musical instruments: humidity expands a wooden instrument, and dryness contracts it. Of these factors, dryness is the most harmful, since the contraction of the wood actually pulls the instrument apart. Much energy has been expended over the centuries in investigations of various varnishes, shellacs, glues, and sealers. Many makers prefer to make their instruments in dry conditions, for the expansion caused by humidity is unlikely to prove as harmful as the contraction caused by dryness.
Aside from a family of Southeast Asian instruments known as boat lutes—which, by definition, are hewn from a single block of wood—and a few other chordophones, including the Japanese biwa (a lute), portions of the koto (a zither), and often the Puerto Rican cuatro (a lute)—the bodies of most wooden instruments are constructed from multiple pieces of wood. The instruments are built up of many pieces of wood glued together; the shaping of curved pieces is accomplished by gouging and planing (as in the belly of the violin) or by heating and pressing in a frame (the sides of the violin or guitar). Soundboards, the most important part of the resonance system of stringed instruments, are carefully planed to close tolerances. Mass-production methods are unsuitable for the production of high-quality chordophones because no two pieces of wood are precisely alike in their acoustical qualities; each piece of wood requires special judgment and treatment. Ideally, therefore, stringed instruments of the highest quality must be individually made. Piano manufacture is a partial exception to this rule, but even in a piano factory, individual treatment and craftsmanship are allowed full sway. The modern piano is a product of several different factories. The cast-iron frames are made by specialized foundries, and the steel strings, the keyboards, and the actions (mechanisms for striking the strings) are produced by specialized firms. Each of these processes requires an experienced artisan, and the work of assembly, polishing, tuning, and tone regulation calls for hours of individual attention to each instrument.
Strings (Urdu: اِسٹرنگز) was a Pakistani pop/rock band composed of two members, plus four live band members from Karachi, Pakistan. The band was initially formed by four college students— Bilal Maqsood (vocals and guitars), Faisal Kapadia (vocals), Rafiq Wazir Ali (synthesizer) and Kareem Bashir Bhoy (bass guitar)—in 1988. [1]

String instrument. Some string instruments. 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.
What are string instruments? Meet the members of the string family. As their name suggests, stringed instruments use vibrated strings to produce sound – but how are these instruments played and what are the different types?
A string is the vibrating element of chordophones such as the guitar, harp, piano ( piano wire ), and the violin family, that produces sound. Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but with control.
