Double Bass




The Double Bass

The double bass (also known as the contrabass, string bass, upright bass, bull fiddle, or simply bass) is the largest and lowest pitched bowed string instrument used in the modern symphony orchestra. It is used extensively in Western classical music as a standard member of the string section of symphony orchestras and smaller string ensembles. In addition, it is used in other genres such as jazz, blues, rock and roll, rockabilly, psychobilly, and bluegrass. Like many other string instruments, the double bass is played either with a bow (arco) or by plucking the strings (pizzicato).

The double bass is generally (possibly mistakenly) regarded as the only modern descendant of the viola da gamba family of instruments, a family which originated in Europe in the 15th century, and as such it has been described as a "bass viol." Before the 20th century many double basses had only three strings, in contrast to the five to six strings typical of instruments in the viola da gamba family or the four strings of instruments in the violin family. Some existing instruments, such as those by Gasparo da Salò, were converted from sixteenth-century six-string contrabass violoni.

The double bass's proportions are dissimilar to those of the violin and cello; for example, it is deeper (the distance from top to back is proportionally much greater than the violin). In addition, while the violin has bulging shoulders, most double basses have shoulders carved with a more acute slope, like members of the viola da gamba family. Many very old double basses have had their shoulders cut or sloped to aid playing with modern techniques. Before these modifications, the design of their shoulders was closer to instruments of the violin family.

The double bass is the only modern bowed string instrument that is usually tuned in fourths (like viols), rather than fifths (see Tuning, below). The issue of the instrument's exact lineage is still a matter of some debate, and the supposition that the double bass is a direct descendant of the viola da gamba family is an issue that has not been entirely resolved.

In his A New History of the Double Bass, Paul Brun asserts, with many references, that the double bass has origins as the true bass of the violin family. He states that, while the exterior of the double bass may resemble the viola da gamba, the internal construction of the double bass is nearly identical to that of other instruments in the violin family, and is very different from the internal structure of viols

Cello


Cello

The violoncello, usually abbreviated to cello, or 'cello, plural celli (the c is pronounced as in the ch in "chips") is a bowed stringed instrument. A person who plays a cello is called a cellist. The cello is used as a solo instrument, in chamber music, and as a member of the string section of an orchestra.

The name cello is an abbreviation of the Italian violoncello, which means "little violone", referring not to the double bass but to the slightly larger (and now uncommon) instrument the bass violin which was sometimes tuned a whole step lower than the cello.

The cello is most closely associated with European classical music. It is part of the standard orchestra and is the bass voice of the string quartet, as well as being part of many other chamber groups. A large number of concertos and sonatas have been written for it. It is less common in popular music, but is sometimes featured in pop and rock recordings. The cello has also been modified for Indian classical music by Saskia Rao-de Haas.

Among the most famous Baroque works for the cello are J. S. Bach's six unaccompanied Suites. In the Classical era the two concertos by Joseph Haydn in C major and D major stand out. Romantic era repertoire includes the Concerto by Antonín Dvořák, Elgar's Cello Concerto in E minor, and the two sonatas by Brahms. Compositions from the early 20th century include unaccompanied cello sonatas by Zoltán Kodály (Op.8), Paul Hindemith (Op.25) and W.H. Squire . The cello's versatility made it popular with composers in the mid- to late twentieth century, encouraged by soloists who specialized in contemporary music (such as Siegfried Palm and Mstislav Rostropovich) commissioning from and collaborating with composers.

The cello has four strings referred to either by number or by their standard tuning, which is in perfect fifth intervals: the A string (I, the highest sounding), D string (II), G string (III), and C string (IV, the lowest sounding). The A string is tuned to the pitch A3 (just below middle C), the D string a fifth lower at D3, the G string a fifth below that at G2, and the C string tuned to C2 (two octaves lower than middle C). The strings are one octave lower than the viola, and one octave plus one fifth lower than the violin.

Some pieces require an altered tuning of the strings known as scordatura, The two most well-known examples are the fifth of Bach's 6 Suites for Unaccompanied Cello (C2-G2-D3-G3) and Zoltán Kodály's Sonata opus 8 (B1-F♯2-D3-A3). The sixth of Bach's 6 Suites for Unaccompanied Cello was written for an instrument with five strings tuned C2-G2-D3-A3-E4. This may be the violoncello piccolo, a smaller cello with five strings that fell out of use in the mid-eighteenth century.

The range of the cello is limited at the lower end by the tuning of the lowest string; at the upper end it varies. A comfortable upper limit for professional cellists is C6 (two octaves above middle C), although up to one extra octave is available. The highest stopped pitch on the fingerboard is somewhere around F♯6, but some composers have written higher: for example, Zoltán Kodaly's Sonata opus 8 requires a B6 to be played in the concluding measures.

Music for the cello is written in bass clef with changes to tenor clef or treble clef when necessary to avoid too many ledger lines. Composers before about 1900 usually followed an older convention which largely avoided use of the tenor clef, writing instead in the treble clef with notes sounding an octave lower than written; except when the treble clef followed a passage in tenor clef, when it was to be played at the written pitch. A late example of this usage is the trio arrangement attributed to Hans Eisler of the Serenade from Schoenberg's Septet op. 24.

Body position

The cello is played while seated. Its weight is supported mainly by its endpin or spike, which rests on the floor; it is steadied on the lower bout between the knees of the seated player, and on the upper bout against the upper chest. The neck of the cello is above the player's left shoulder. The bow is drawn horizontally across the strings. In early times, female cellists sometimes played side-saddle, since it was considered improper for a lady to part her knees in public. A player's handedness does not alter the way the cello is held or used. In exceedingly rare cases the cello has been played in a mirror-image posture: this is usually because of a physical disability of one of the player's arms or hands which makes the required technique impossible for that side of the body. In such a situation, the player must decide whether or not to reverse the set-up of the cello (the string positions, bass-bar, sound post, fingerboard shape, and bridge carving are all asymmetrical).



Viola

Viola

BASIC

The viola (French, alto; German Bratsche) is a bowed string instrument. It is the middle voice of the violin family, between the upper voice of the violin and the lower voice of the cello.

The casual observer may mistake the viola for the violin because of their similarity in size, closeness in pitch range (the viola is a perfect fifth below the violin), and identical playing position. However, the viola's timbre sets it apart: its rich, dark-toned sonority is more full-bodied than the violin's. The viola's mellow voice is frequently used for playing inner harmonies, and it does not enjoy the wide solo repertoire or fame of the violin.

The name of the instrument is properly pronounced "vee-oh-la" (but often incorrectly pronounced "vye-oh-la" as the woman's name "Viola" is spoken).

The parts of a Viola are the exact same as a violin except that it's larger and it is more variable in proportion.

Historically, the viola was used less often for solo concerti and sonatas than the violin and the cello. This was often attributed to its sound, which, being mellower and perhaps less sharp than that of the violin, was said to be less suited to virtuoso display.

Bach, Mozart and Beethoven, Dvorak, Glinka and more were great viola composers and were considered famous.

About Violins


Violins

Basic

The violin is a bowed string instrument with four strings tuned in perfect fifths. It is the smallest and highest pitched member of the violin family of string instruments, which also includes the viola and cello and sometimes the double bass.

A violin is sometimes informally called a fiddle, no matter what kind of music is played on it. The word "violin" comes to us through the Romance languages from the Middle Latin word vitula, meaning "stringed instrument”.

A person who plays the violin is called a violinist or fiddler, and a person who makes or repairs them is called a luthier, or simply a violin maker.

History

The earliest stringed instruments were mostly plucked. Bowed instruments may have originated in the cultures of Central Asia, an example being the Mongolian instrument Morin huur:
Turkic and Mongolian horsemen from Inner Asia were probably the world’s earliest fiddlers. Their two stringed upright fiddles are strung with horsehair strings, played with horsehair bows, and often feature a carved horse’s head at the end of the neck. ... The violins, violas, and cellos we play today, and whose bows are still strung with horsehair, are a legacy of the nomads.

It is believed that these instruments eventually spread to China, India, and the Middle East, where they developed into instruments such as the Erhu (Chinese) and Rebab (Middle East), and Esraj (India). The violin in its present form emerged in the early 16th century, in Northern Italy, where the port towns of Venice and Genoa maintained extensive ties through the trade routes of the Mongol Empire.

Most likely, the first makers of violins were formed from three types of current instruments: the rebec, in use since the 10th century (itself derived from the Arabic rebab), the Renaissance fiddle, and the lira da braccio. One of the earliest descriptions of the instrument, including its tuning, was in the Epitome musical by Jambe de Fer, published in Lyon in 1556. By this time, the violin had already begun to spread throughout Europe.

The oldest documented violin to have four strings, like the modern violin, was constructed in 1555 by Andrea Amati. The violin immediately became very popular, both among street musicians and the nobility, illustrated by the fact that the French king Charles IX ordered Amati to construct 24 violins for him in 1560. The oldest surviving violin, dated inside, is from this set, and is known as the "Charles IX," made in Cremona c. 1560. "The Messiah" or "Le Messie" made by Antonio Stradivari in 1716 remains pristine, never having been used. It is now located in the Ashmolean Museum of Oxford.

Significant changes occurred in the construction of the violin in the 18th century, particularly in the length and angle of the neck, as well as a heavier bass bar. The majority of old instruments have undergone these modifications, and hence are in a significantly different state than when they left the hands of their makers, doubtless with differences in sound and response. But these instruments in their present condition set the standard for perfection in violin craftsmanship and sound, and violin makers all over the world try to come as close to this ideal as possible.

To this day, the Violin is a precious and essential instrument to the history of music because it has been evolved from various kinds of instruments.

TUNING
Violins are tuned by turning the pegs in the pegbox under the scroll, or by adjusting the fine tuner screws at the tailpiece. All violins have pegs; fine tuners (also called fine adjusters) are optional. Most fine tuners consist of a metal screw that moves a lever to which the string is attached. They permit very small pitch adjustments with much more ease than the pegs.

Fine tuners are usually used with solid metal or composite strings that may be difficult to tune with pegs alone; they are not used with gut strings, which are more elastic and don't respond adequately to the very small movements of fine tuners. Some violinists have fine tuners on all 4 strings; most classical players have only a single fine tuner on the E string. Most violinists prefer one fine tuner because fine tuners often can damage the top of the violin.

To tune a violin, the A string is first tuned to a standard pitch (usually 440 Hz), using either a tuning device or another instrument. (When accompanying a fixed-pitch instrument such as a piano or accordion, the violin tunes to it.) The other strings are then tuned against each other in intervals of perfect fifths by bowing them in pairs. A minutely higher tuning is sometimes employed for solo playing to give the instrument a brighter sound; conversely, Baroque music is sometimes played using lower tunings to make the violin's sound more gentle. After tuning, the instrument's bridge may be examined to ensure that it is standing straight and centered between the inner nicks of the f-holes; a crooked bridge may significantly affect the sound of an otherwise well-made violin.

The tuning G-D-A-E is used for most violin music. Other tunings are occasionally employed; the G string, for example, can be tuned up to A. The use of nonstandard tunings in classical music is known as scordatura; in some folk styles, it is called "cross-tuning." One famous example of scordatura in classical music is Saint-Saëns' Danse Macabre, where the solo violin's E string is tuned down to E flat to impart an eerie dissonance to the composition. Another example would be in the third movement of Contrasts, by Béla Bartók, where the E string is tuned down to E flat and the G tuned to a G sharp.

While most violins have four strings, there are some instruments with five,[11] six, or even seven strings. The extra strings on such violins typically are lower in pitch than the G-string; these strings are usually tuned to C, F, and B flat. If the instrument's playing length, or string length from nut to bridge, is equal to that of an ordinary full-scale violin (i.e., a bit less than 13 inches, or 330 mm), then it may be properly termed a violin. Some such instruments are somewhat longer and should be regarded as violas. Violins with five strings or more are often used in jazz or folk music.

Violin has to be constructed to with stand the strong downward force exerted by its 4 strings on the bridge, which can weigh to as much as 7.7kg!
