The name cello is an abbreviation of the Italian violoncello, which means "little violone". 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. Among the most famous 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 in A minor, the Concerto by Antonin Dvorák, and the two sonatas by Brahms. Compositions from the early 20th century include Elgar's Cello Concerto in E minor, unaccompanied cello sonatas by Zoltan Kodaly (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 Seigfried Palm and Mstislav Rostropovich) commissioning from and collaborating with composers.
The cello has four strings, which are 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 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.
The cello is typically made from wood, although other materials such as carbon fibre 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.
Cello manufacturer Luis & Clark constructs cellos from carbon fiber. Carbon fiber cellos are particularly suitable for outdoor playing because of the strength of the material and its resistance to humidity and temperature fluctuations.
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 on a cello have cores made out of gut, metal, or synthetic materials, such as Perlon. Cellists may mix different types of strings on their instruments. 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. Modern endpins are retractable and adjustable; older ones were removed when not in use.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 holds the strings above the cello and transfers their vibrations to the top of the instrument and the soundpost inside (see below). 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.
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.
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)
Cellos are part of the standard symphony orchestra. Usually, the orchestra includes eight to twelve cellists. The cello section, in standard orchestral seating, is located on stage left (the audience's right) in the front, opposite the first violin section. However, some orchestras and conductors prefer switching the positioning of the viola and cello sections. The principal, or "first chair" cellist is the section leader, determining bowing's for the section in conjunction with other string principals, and playing solos. Principal players always sit closest to the audience.
The cellos are a critical part of orchestral music; all symphonic works involve the cello section, and many pieces require cello soli or solos. Much of the time, cellos provide part of the harmony for the orchestra. On many occasions, the cello section will play the melody for a brief period of time, before returning to the harmony. There are also cello concertos, which are orchestral pieces in which a featured, solo cellist is accompanied by an entire orchestra.
