No. 10 is the bass bar.

In a string instrument, the bass bar is a brace running from the foot of the neck to a position under the bridge, which bears much of the tension of the strings. Bass bars are used:

String instrument musical instrument that generates tones by one or more strings stretched between two points

String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner.

The neck is the part of certain string instruments that projects from the main body and is the base of the fingerboard, where the fingers are placed to stop the strings at different pitches. Guitars, banjos, ukuleles, lutes, the violin family, and the mandolin family are examples of instruments which have necks. Necks are also an integral part of certain woodwind instruments, like for instance the saxophone.

Bridge (instrument) device for supporting the strings on a stringed 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, metal or other materials. The bridge supports the strings and holds them over the body of the instrument under tension.

Violin family class of stringed instruments

The violin family of musical instruments was developed in Italy in the 16th century. At the time the name of this family of instruments was viole da braccio which was used to distinguish them from the viol family. The standard modern violin family consists of the violin, viola, cello, and double bass.

Archtop guitar type of steel-stringed acoustic or semi-acoustic guitar

An "archtop guitar" is a hollow steel-stringed acoustic or semiacoustic guitar with a full body and a distinctive arched top, whose sound is particularly popular with jazz, blues, rockabilly, and psychobilly guitarists.

and in many other string instruments.

According to the A Dictionary of Music and Musicians by George Grove: [1]

George Grove English writer on music and director of the Royal College of Music

Sir George Grove was an English writer on music, known as the founding editor of Grove's Dictionary of Music and Musicians.

BASS-BAR, an oblong piece of wood, fixed lengthwise inside the belly of the various instruments belonging to the violin-tribe, running in the same direction with the strings, below the lowest string , and acting as a beam or girder to strengthen the belly against the pressure of the left foot of the bridge , as the sound-post does against that of the right foot (in a right handed instrument). It is the only essential part of the instrument which, owing to the gradual elevation of the pitch, has had to undergo an alteration since Stradivari's time. Tartini states, in the year 1734, that the tension of the strings on a violin was equal to a weight of 63 lb (29 kg), while nowadays it is calculated at more than 80 lb (36 kg). (Other modern value: c. 22 kg / 220 N according to string manufacturers' data.) This enormous increase in pressure requires for the belly a proportionate addition of bearing-power, and this could only be given by strengthening the bass-bar, which has been done by giving it a slight additional depth at the centre, and adding considerably to its length. In consequence of this we hardly ever find in an old instrument the original bass-bar of the maker, just as rarely as the original sound-post or bridge, all of which however can be made as well by any experienced living violin-maker as by the original Stradivari or Amati. —P.D.

Cello musical instrument

The cello ( CHEL-oh; plural cellos or celli) or violoncello ( VY-ə-lən-CHEL-oh; Italian pronunciation: [vjolonˈtʃɛllo]) is a string instrument. It is played by bowing or plucking its four strings, which are usually tuned in perfect fifths an octave lower than the viola: from low to high, C2, G2, D3 and A3. It is the bass member of the violin family, which also includes the violin, viola and the double bass, which doubles the bass line an octave lower than the cello in much of the orchestral repertoire. After the double bass, it is the second-largest and second lowest (in pitch) bowed string instrument in the modern symphony orchestra. The cello is used as a solo instrument, as well as in chamber music ensembles (e.g., string quartet), string orchestras, as a member of the string section of symphony orchestras, most modern Chinese orchestras, and some types of rock bands.

Guitar fretted string instrument

The guitar is a fretted musical instrument that usually has six strings. It is typically played with both hands by strumming or plucking the strings with either a guitar pick or the finger(s)/fingernails of one hand, while simultaneously fretting with the fingers of the other hand. The sound of the vibrating strings is projected either acoustically, by means of the hollow chamber of the guitar, or through an electrical amplifier and a speaker.

Harmonic

A harmonic is any member of the harmonic series. The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields. It is typically applied to repeating signals, such as sinusoidal waves. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called the 1st harmonic, the following 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. 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, 150 Hz, 200 Hz and any addition of waves with these frequencies is periodic at 50 Hz.

An nth characteristic mode, for n > 1, will have nodes that are not vibrating. For example, the 3rd characteristic mode will have nodes at L and L, where L is the length of the string. In fact, each nth characteristic mode, for n not a multiple of 3, will not have nodes at these points. These other characteristic modes will be vibrating at the positions L and L. If the player gently touches one of these positions, then these other characteristic modes will be suppressed. The tonal harmonics from these other characteristic modes will then also be suppressed. Consequently, the tonal harmonics from the nth characteristic modes, where n is a multiple of 3, will be made relatively more prominent.

Pizzicato Playing technique for string instruments

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:

Crwth Welsh musical instrument

The crwth, also called a crowd or rote, is a bowed lyre, a type of stringed instrument, associated particularly with Welsh music and with medieval folk music of England, now archaic but once widely played in Europe. Four historical examples have survived and are to be found in St Fagans National Museum of History (Cardiff), National Library of Wales (Aberystwyth), Warrington Museum & Art Gallery, and the Museum of Fine Arts, Boston.

In music, a bow is a tensioned stick with hair affixed to it that is moved across some part of a musical instrument to cause vibration, which the instrument emits as sound. The vast majority of bows are used with string instruments, such as the violin, although some bows are used with musical saws and other bowed idiophones.

Sound board (music) musical instrument part

A sound board, or soundboard, is the surface of a string instrument that the strings vibrate against, usually via some sort of bridge. Pianos, guitars, banjos, and many other stringed instruments incorporate soundboards. The resonant properties of the sound board and the interior of the instrument greatly increase the loudness of the vibrating strings.

Scordatura[skordaˈtuːra], is a tuning of a stringed instrument different from the normal, standard tuning. It typically attempts to allow special effects or unusual chords or timbre, or to make certain passages easier to play. It is common to notate the finger position as if played in regular tuning, while the actual pitch resulting is altered. When all the strings are tuned by the same interval up or down, as in the case of the viola in Mozart's Sinfonia Concertante for Violin, Viola and Orchestra, the part is transposed as a whole.

Luthier person making or repairing string musical instruments

A luthier is someone who builds or repairs string instruments generally consisting of a neck and a sound box. The word "luthier" comes from the French word luth, which means lute. A luthier was originally a maker of lutes, but the term now includes makers of stringed instruments such as the violin or guitar. A luthier does not make harps or pianos, as these require different skills and construction methods because their strings are secured to a frame.

Machine head apparatus for tuning stringed musical instruments

A machine head is a geared apparatus for tuning stringed musical instruments by adjusting string tension. Machine heads are used on mandolins, guitars, double basses, and others, and are usually located on the instrument's headstock. Other names for guitar tuners include pegs, gears, machines, cranks, knobs, tensioners, and tighteners.

Violin making and maintenance

Making an instrument of the violin family may be done in different ways, many of which have changed very little in nearly 500 years since the first violins were made. Some violins, called "bench-made" instruments, are made by a single individual, either a master maker, or an amateur working alone. Several people may participate in the making of a "shop-made" instrument, working under the supervision of a master. Various levels of "trade violin" exist, often mass-produced by workers who each focus on a small part of the overall job, with or without the aid of machinery.

Violin construction and mechanics

A violin consists of a body or corpus, a neck, a finger board, a bridge, a soundpost, four strings, and various fittings. The fittings are the tuning pegs, tailpiece and tailgut, endpin, possibly one or more fine tuners on the tailpiece, and usually a chinrest, either attached directly over the tailpiece or to the left of it.

Violin technique

Playing the violin entails holding the instrument under the chin, supported by the left shoulder. 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 notes.

History of the violin Wikimedia history article

The violin, viola, and cello were first made in the early 16th century, in Italy. The earliest evidence for their existence is in paintings by Gaudenzio Ferrari from the 1530s, though Ferrari's instruments had only three strings. The Academie musicale, a treatise written in 1556 by Philibert Jambe de Fer, gives a clear description of the violin family much as we know it today.

Basic physics of the violin

The sound of a violin is the result of interactions between its many parts. Drawing a bow across the strings causes the strings to vibrate. This vibration is transmitted through the bridge and sound post to the body of the violin, which allows the sound to effectively radiate into the surrounding air. The tension and type of strings, placement and tension of the sound post, quality of the bow, and the construction of the body, all contribute to the loudness and tonal quality of the sound.

Samuel Zygmuntowicz is an award-winning contemporary luthier. He began his instrument making training at age 13, and studied making and restoration under Peter Prier, Carl Becker and René Morel. Since 1985 he has been based in Brooklyn, New York. His early work demonstrates expert skill as a copyist of classic instruments. Later work includes personal models informed by intensive advanced research. Findings from this research have been published in numerous print and digital media. Zygmuntowicz is an active fiddler, playing with several folk music groups. His playing can be heard on the recordings Grand Picnic, and Jump When the Trumpets Blow.
