Luigi Boccherini, born on this date in 1743, was a cellist and the prolific composer of more than 400 works: these included four cello concertos, about 90 string quartets and about 125 string quintets (more string quintets than any other composer). Most of his string quintets were written for two violins, one viola and two cellos. Boccherini's most famous piece is the minuet from his "String Quintet in E, Opus 13." It has been used as background music in dozens of films, including In Her Shoes, Shanghai Knights, Ace Ventura: When Nature Calls and The Time of Their Lives.

"Cello"
The name cello is an abbreviation of the Italian violoncello, which means "little violone", referring to the violone ("big viol"), the lowest-pitched instrument of the viol family, the group of string instruments that were superseded by the violin family. Thus, the name carries both an augmentative "-one" ("big") and a diminutive "-cello" ("little"). Cellos are tuned in fifths, starting with C2 (two octaves below middle C) as the lowest string, followed by G2, D3, and A3. It is tuned the same way as the viola, only an octave lower.

The cello is most closely associated with European classical music, and has been described as the closest sounding instrument to the human voice. The instrument is a 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 the cello. The instrument is less common in popular music, but is sometimes featured in pop and rock recordings. The cello has also recently appeared in major hip-hop and R & B performances, such as singers Rihanna and Ne-Yo's performance at the American Music Awards. The instrument has also been modified for Indian classical music by Nancy Lesh and Saskia Rao-de Haas.

Among the most well-known Baroque works for the cello are J. S. Bach's six unaccompanied Suites. From the Classical era, the two concertos by Joseph Haydn in C major and D major stand out, as do the five sonatas for cello and pianoforte of Beethoven which span the important three periods of his compositional evolution. Romantic era repertoire includes the Schumann Concerto, the Dvořák Concerto and the two sonatas by Brahms. Compositions from the early 20th century include Elgar's Cello Concerto in E minor, unaccompanied cello sonatas by Zoltán Kodály and Paul Hindemith. The cello's versatility made it popular with composers in the mid- to late twentieth century such as Prokofiev, Shostakovich, Britten, Ligeti and Dutilleux, encouraged by soloists who specialized in contemporary music (such as Siegfried Palm and Mstislav Rostropovich) commissioning from and collaborating with composers.

Violoncello da spalla
The violoncello da spalla (sometimes "violoncello piccolo da spalla" or "violoncello da span") was the first cello referred to in print (by Jambe de Fer in 1556). "Violone" means a larger "viola" (viol), while "-cello" in Italian is a diminutive and spalla means "shoulder" in Italian so that violoncello da spalla suggest a "little big violin" that may be held on the shoulder so that the player could perform while walking or that the early, short-necked instrument was hung across the shoulder by a strap. By the turn of the twentieth century, it had grown customary to abbreviate the name violoncello to 'cello, with the apostrophe indicating the six missing prefix letters. It now is acceptable to use the name "cello" without the apostrophe and as a full designation.

Body
The cello is typically made from wood, although other materials such as carbon fiber or aluminum may be used. A traditional cello has a spruce top, with maple for the back, sides, and neck. Other woods, such as poplar or willow, are sometimes used for the back and sides. Less expensive cellos frequently have tops and backs made of laminated wood.

The top and back are traditionally hand-carved, though less expensive cellos are often machine-produced. The sides, or ribs, are made by heating the wood and bending it around forms. The cello body has a wide top bout, narrow middle formed by two C-bouts, and wide bottom bout, with the bridge and sound holes just below the middle.

The top and back of the cello has decorative border inlay known as purfling. Purfling looks attractive, but is not just for decoration. If a cello is dropped or bumped against something so that damage occurs, the purfling can stop cracks from forming. A crack may form at the rim of the instrument, but will spread no further. Without purfling, cracks can spread up or down the top or back. Playing, traveling and the weather all affect the cello and can increase a crack if purfling is not in place. Less expensive instruments typically have the purfling painted on.

Neck, pegbox, and scroll
Above the main body is the carved neck, which leads to a pegbox and the scroll. The neck, pegbox, and scroll are normally carved out of a single piece of wood. Attached to the neck and extending over the body of the instrument is the fingerboard. The nut is a raised piece of wood, where the fingerboard meets the pegbox, which the strings rest on. The pegbox houses four tuning pegs, one for each string. The pegs are used to tune the cello by either tightening or loosening the string. The scroll is a traditional part of the cello and all other members of the violin family. Ebony is usually used for the tuning pegs, fingerboard, and nut, but other hard woods, such as boxwood or rosewood, can be used.

Strings
Strings on a cello have cores made out of gut, metal, or synthetic materials, such as Perlon. Most modern strings used today are also wound with metallic materials like aluminum, titanium and chromium. Cellists may mix different types of strings on their instruments.

Tailpiece and endpin
The tailpiece and endpin are found in the lower part of the cello. The tailpiece is traditionally made of ebony or another hard wood, but can also be made of plastic or steel. It attaches the strings to the lower end of the cello, and can have one or more fine tuners. The endpin or spike is made of wood, metal or rigid carbon fiber and supports the cello in playing position. In the Baroque period the cello was held between the calves. Around the 1830s, the Belgian cellist Auguste Adrien Servais introduced the endpin and propagated its use. Modern endpins are retractable and adjustable; older ones were removed when not in use. (The word "endpin" sometimes also refers to the button of wood located at this place in all instruments in the violin family, but this is usually called "tailpin". The sharp tip of the cello's endpin is sometimes capped with a rubber tip that protects the tip from dulling and prevents the cello from slipping on the floor.

The bridge of a cello, with a mute
The bridge holds the strings above the cello and transfers their vibrations to the top of the instrument and the soundpost inside. The bridge is not glued, but rather held in place by the tension of the strings. The f-holes, named for their shape, are located on either side of the bridge, and allow air to move in and out of the instrument as part of the sound-production process. The f-holes also act as access points to the interior of the cello for repairs or maintenance. Sometimes a small hose containing a water-soaked sponge, called a Dampit, is inserted through the f-holes, and serves as a humidifier.

Internal features
Internally, the cello has two important features: a bass bar, which is glued to the underside of the top of the instrument, and a round wooden sound post, which is wedged between the top and bottom plates. The bass bar, found under the bass foot of the bridge, serves to support the cello's top and distribute the vibrations. The sound post, found under the treble side of the bridge, connects the back and front of the cello. Like the bridge, the sound post is not glued, but is kept in place by the tensions of the bridge and strings. Together, the bass bar and sound post transfer the strings' vibrations to the top (front) of the instrument (and to a lesser extent the back), acting as a diaphragm to produce the instrument's sound.

Glue
Cellos are constructed and repaired using hide glue, which is strong but reversible, allowing for disassembly when needed. Tops may be glued on with diluted glue, since some repairs call for the removal of the top. Theoretically, hide glue is weaker than the body's wood, so as the top or back shrinks side-to-side, the glue holding it will let go, avoiding a crack in the plate.

A cello bow
Traditionally, bows are made from pernambuco or brazilwood. Both come from the same species of tree (Caesalpina echinata), but pernambuco, used for higher-quality bows, is the heartwood of the tree and is darker in color than brazilwood (which is sometimes stained to compensate). Pernambuco is a heavy, resinous wood with great elasticity which makes it an ideal wood for instrument bows.

Bow sticks are also made from carbon-fiber, which is stronger than wood. Inexpensive, low-quality student bows are often made from fiberglass. An average cello bow is 73 cm long (shorter than a violin or viola bow) 3 cm high (from the frog to the stick) and 1.5 cm wide. The frog of a cello bow typically has a rounded corner like that of a viola bow, but is wider. A cello bow is roughly 10 grams heavier than a viola bow, which in turn is roughly 10 g heavier than a violin bow.
The bow hair is horsehair, though synthetic hair in different colors is also available. The hair is coated with rosin by the player to make it grip the strings and cause them to vibrate. Bows need to be re-haired periodically, especially if the hairs break frequently or lose their gripping quality. The hair is kept under tension while playing by a screw which pulls the frog (the part of the bow under the hand) back.

Development
The cello developed from the bass violin, first referred to by Jambe de Fer in 1556, which was originally a three-string instrument. The first instance of a composer specifying the bass violin may have been Gabrieli in Sacrae symphoniae, 1597.[citation needed] Monteverdi referred to the instrument as "basso de viola da braccio" in Orfeo (1607). Although the first bass violin, possibly invented by Amati as early as 1538, was most likely inspired by the viol, it was created to be used in consorts with the violin. The bass violin was actually often referred to as a "violone," or "large viola," as were the viols of the same period. Instruments that share features with both the bass violin and the viola de gamba appear in Italian art of the early 1500s...

The invention of wire-wound strings (fine wire around a thin gut core), around 1660 in Bologna, allowed for a finer bass sound than was possible with purely gut strings on such a short body. Bolognese makers exploited this new technology to create the cello, a somewhat smaller instrument suitable for solo repertoire due to both the timbre of the instrument and the fact that the smaller size made it easier to play virtuosic passages. This instrument had disadvantages as well, however. The cello's light sound was not as suitable for church and ensemble playing, so it had to be doubled by basses or violones.

Around 1700, Italian players popularized the cello in northern Europe, although the bass violin (basse de violon) continued to be used for another two decades in France.[citation needed] Many existing bass violins were literally cut down in size in order to convert them into cellos according to the smaller pattern cello as developed by Stradivari, who also made a number of old pattern large cello's (the 'Servais').[4] The bass violin remained the "most used" instrument in England as late as 1740, where the violoncello was still "not common." The sizes, names, and tunings of the cello varied widely by geography and time. The size was not standardized until around 1750.

Despite similarities to the viola da gamba, the cello is actually part of the viola da braccio family, meaning "viol of the arm", which includes, among others, the violin and viola. Though paintings like Bruegel's "The Rustic Wedding" and de Fer in his Epitome Musical suggest that the bass violin had alternate playing positions, these were short-lived and the more practical and ergonomic a gamba position eventually replaced them entirely.

Baroque era cellos differed from the modern instrument in several ways. The neck has a different form and angle which matches the baroque bass-bar and stringing. Modern cellos have an endpin at the bottom to support the instrument (and transmit some of the sound through the floor), while Baroque cellos are held only by the calves of the player. Modern bows curve in and are held at the frog; Baroque bows curve out and are held closer to the bow's point of balance. Modern strings normally have a metal core, although some use a synthetic core; Baroque strings are made of gut, with the G and C strings wire-wound. Modern cellos often have fine-tuners connecting the strings to the tailpiece, which make it much easier to tune the instrument. Overall, the modern instrument has much higher string tension than the Baroque cello, resulting in a louder, more projecting tone, with fewer overtones.

No educational works specifically devoted to the cello existed before the 18th century, and those that do exist contain little value to the performer beyond simple accounts of instrumental technique. The earliest cello manual is Michel Corrette's Méthode, thèorique et pratique pour apprendre en peu de temps le violoncelle dans sa perfection (Paris, 1741).

Playing technique
Seated Cellist

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, and the C-String tuning peg is just behind the left ear. 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).

Left hand technique
The position of the left hand fingers along the strings determine the pitch of the note. The closer to the bridge that the string is depressed, the higher in pitch will be the resulting sound, because the vibrating string length has been shortened. In the neck positions (which use just less than half of the fingerboard, nearest the top of the instrument), the thumb rests on the back of the neck; in thumb position (a general name for notes on the remainder of the fingerboard) the thumb usually rests alongside the fingers on the string and the side of the thumb is used to play notes. The fingers are normally held curved with each knuckle bent, with the fingertips in contact with the string. If a finger is required on two (or more) strings at once to play perfect fifths (in double stops or chords) it is used flat. In slower, or more expressive playing, the contact point can move slightly away from the nail to the pad of the finger, allowing a fuller vibrato.

Vibrato
Vibrato is a small oscillation in the pitch of a note, usually considered expressive. It is created by a partial rotation of the upper arm at the shoulder joint, which translates into a linear oscillation of the lower arm. The fixed point of contact of the fingertip on the string absorbs this motion by rocking back and forth. It is this change in the attitude of the fingertip to the string which causes the pitch to vary. Vibrato is a key expressive device, and a well-developed vibrato technique is an essential element of a modern cellist's skill. In some styles of music, such as that of the Romantic period, vibrato may be used on almost every note. However, in other styles, such as Baroque repertoire, vibrato is used only rarely, as an ornament. In any case, the choice of whether to use vibrato, and how much, is normally a stylistic decision on the part of the player. Typically, the lower the pitch of the note played, the wider and slower the vibrato.

Harmonics
Harmonics played on the cello fall into two classes; natural and artificial. Natural harmonics are produced by lightly touching (but not depressing) the string with the finger at certain places, and then bowing (or, rarely, plucking) the string. For example, the halfway point of the string will produce a harmonic that is one octave above the unfingered (open) string. Natural harmonics only produce notes that are part of the harmonic series for the string on which they occur. Artificial harmonics (also called False harmonics), in which the player depresses the string fully with one finger while touching the same string lightly with another finger, can produce any notes above middle C. They usually appear with the touching note a perfect fourth above the stopped note, which produces a sound two octaves above the stopped note, although other intervals are available. All harmonics produce a distinctive flute-like sound, and are usually performed without vibrato.

Glissando
Glissando ("sliding", in Italian) is an effect played by sliding the finger up or down the fingerboard without releasing the string. This causes the pitch to rise and fall smoothly, without separate, discernible steps.

Right hand technique
In cello playing, the bow is much like the breath of a wind instrument player. Arguably, it is the major determinant in the expressiveness of the playing. The right hand holds the bow and controls the duration and character of the notes. The bow is drawn across the strings roughly halfway between the end of the fingerboard and the bridge, in a direction perpendicular to the strings. The bow is held with all five fingers of the right hand, the thumb opposite the fingers and closer to the cellist's body. The shape of the hand should resemble that of its relaxed state, with all fingers curved, including the thumb. The transmission of weight from the arm to the bow happens through the pronation (inward rotation) of the forearm, which pushes the index finger and to a lesser degree the middle finger onto the bow. The necessary counterforce is provided by the thumb. Depending upon the school of training, the other two fingers are used in various degrees to help maintain the angle of the bow to the string and are critical to controlling the bow when it is off the string.

In English, the terminology for bow direction (down and up) can be misleading. A downbow is drawn to the right of the player, and an upbow to the left. A downbow is drawn by first using the upper arm, then the forearm, then the wrist (turning slightly inward) in order to maintain a straight stroke. An upbow is drawn by moving first the forearm, then the upper arm, then the wrist (pushing slightly upward). The bow is mostly used perpendicular to the string being played. In order to perform string changes the whole arm is either lowered or lifted, with as little wrist movement as possible in order to maintain the angle to the string. However, flexibility of the wrist is necessary when changing the bow direction from up-bow to down-bow and vice versa. For very fast bow movements, the wrist is used to accomplish the horizontal movement of bow. For longer strokes, the arm is used as well as the wrist.

Tone production and volume of sound depend on a combination of several factors. The three most important ones are: bow speed, weight applied to the string, and point of contact of the bow hair with the string. A good player will be capable of a very even tone, and will counter the natural tendency to play with the most force with the part of the bow nearest to the frog or heel, and the least force near the tip. The closer to the bridge the string is bowed, the more projecting and brighter the tone, with the extreme (sul ponticello) producing a metallic, shimmery sound. If bowing closer to the fingerboard (sul tasto), the sound produced will be softer, more mellow, and less defined.

Double stops
Double stops involve the playing of two notes at the same time. Two strings are fingered simultaneously, and the bow is drawn so as to sound them both at once. Triple and quadruple stops may also be played (in a "broken" fashion), but are difficult to sustain because of the change in slope of the bridge. To extend the technique in this area, Frances-Marie Uitti has invented a two-bow system: one bow plays above the strings and one below, allowing for sustained triple and quadruple stops. However, this technique is very rarely seen or used.

Pizzicato
In pizzicato playing, the string is plucked directly with the fingers or thumb. Usually this is done with the right hand, while the bow is held away from the strings by the rest of the hand or (for extended passages) set down. A single string can be played pizzicato, or double, triple, or quadruple stops can be played. Occasionally, a player must bow one string with the right hand and simultaneously pluck another with the left. This is marked by a "+" above the note. Strumming of chords is also possible, in guitar fashion.

Col legno
Col legno is the technique in which the player uses the wood rather than the hair of the bow on the strings; it takes two different forms, col legno battuto and col legno tratto. Col legno battuto is performed as a percussive technique with no sustaining of the sound. The much less common alternative is col legno tratto, wherein the wood is drawn across the string as the hair is in a normal bow stroke.

Spiccato
In spiccato playing, the strings are not "drawn" by the bow hair but struck by it, while still retaining some horizontal motion, to generate a more percussive, crisp sound. It may be performed by using the wrist to "dip" the bow into the strings. Spiccato is usually associated with lively playing. On a violin, spiccato bowing comes off the string, but on a cello, the wood of the bow may rise briskly up without the hair actually leaving the string. While playing spiccato, the bow is literally bouncing off the string. Cello players simply "dip" the bow into the string, and touch it very fast, and then lift the bow off the string.

Staccato
In staccato, the player moves the bow a small distance and stops it on the string, making a short sound, the rest of the written duration being taken up by silence.

Legato
Legato is a technique where the notes are smoothly connected without accents or breaks.

Sul ponticello/sul tasto
Sul ponticello "on the bridge" refers to bowing closer to the bridge, while sul tasto "on the fingerboard" calls for bowing nearer the end of the fingerboard. Ponticello calls for more bow weight and slower bow speed, and produces a "harder" sound, with strong overtone content. Sul tasto, in extreme cases called "flautando," produces a more flute-like sound, with more emphasis on the fundamental frequency of the note, and softer overtones.
