The cello (/ˈtʃɛloʊ/ CHEL-oh; plural celli or cellos) or violoncello (/ˌvaɪələnˈtʃɛloʊ/ VY-ə-lən-CHEL-oh; Italian pronunciation: ) is a bowed (and occasionally plucked) string instrument of the violin family. Its four strings are usually tuned in perfect fifths: from low to high, C2, G2, D3 and A3, an octave lower than the viola. Music for the cello is generally written in the bass clef, with tenor clef and treble clef used for higher-range passages.

Music for the cello is generally written in the bass clef, with tenor clef and treble clef used for higher-range passages. Played by a cellist or violoncellist, it enjoys a large solo repertoire with and without accompaniment, as well as numerous concerti. The cello often plays the bass part, both in chamber music such as string quartets and the orchestra's string section, where the celli may be reinforced an octave lower by the double basses. Figured bass music of the Baroque-era typically assumes a cello, viola da gamba or bassoon as part of the basso continuo group alongside chordal instruments such as organ, harpsichord), lute or theorbo). Cellos are found in many other ensembles, from modern Chinese orchestras to cello rock bands. The name cello is derived from the ending of the Italian violoncello, which means 'little violone'. Violone ('big viola') was a large-sized member of viol (viola da gamba) family or the violin (viola da braccio) family. The term 'violone' today usually refers to the lowest-pitched instrument of the viols, a family of stringed instruments that went out of fashion around the end of the 17th century in most countries except England and, especially, France, where they survived another half-century before the louder violin family came into greater favour in that country as well. In modern symphony orchestras, it is the second largest stringed instrument (the double bass is the largest). Thus, the name 'violoncello' contained both the augmentative '-one' ('big') and the diminutive '-cello' ('little'). By the turn of the 20th century, it had become common to shorten the name to 'cello, with the apostrophe indicating the missing stem. It is now customary to use 'cello' without apostrophe as the full designation. Viol is derived from the root viola, which was derived from Medieval Latin vitula, meaning stringed instrument. Cellos are tuned in fifths, starting with C2 (two octaves below middle C), followed by G2, D3, and then A3. It is tuned in the same intervals as the viola, but an octave lower. Unlike the violin or viola but similar to the double bass, the cello has an endpin that rests on the floor to support the instrument's weight. The cello is most closely associated with European classical music. The instrument is a part of the standard orchestra, as part of the string section, and is the bass voice of the string quartet (although many composers give it a melodic role as well), as well as being part of many other chamber groups. Among the most well-known Baroque works for the cello are Johann Sebastian Bach's six unaccompanied Suites. The cello possibly figures as a member of the basso continuo group in chamber works by Francesca Caccini (1587–1641), Barbara Strozzi (1619–1677) with pieces such as Il primo libro di madrigali, per 2–5 voci e basso continuo, op. 1 and Elisabeth Jacquet de La Guerre (1665–1729) who wrote six sonatas for violin and basso continuo. 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 Ludwig van Beethoven, which span the important three periods of his compositional evolution. A Divertimento for Piano, Clarinet, Viola and Cello is among the surviving works by Duchess Anna Amalia of Brunswick-Wolfenbüttel (1739–1807). A review of compositions for cello in the Romantic era must include the German composer Fanny Mendelssohn (1805–1847) who wrote the Fantasy in G minor for cello and piano and a Capriccio in A-flat for cello. Other well-known works of the era include the Robert Schumann Concerto, the Antonín Dvořák Concerto as well as the two sonatas and the Double Concerto by Johannes Brahms. Compositions from the late-19th and early 20th century include three cello sonatas (including the Cello Sonata in C Minor written in 1880) by Dame Ethel Smyth (1858–1944), Edward Elgar's Cello Concerto in E minor, Claude Debussy's Sonata for Cello and Piano, and unaccompanied cello sonatas by Zoltán Kodály and Paul Hindemith. Pieces including cello were written by American Music Cente founder Marion Bauer (1882–1955) (two trio sonatas for flute, cello and piano) and Ruth Crawford Seeger (1901–1953) (Diaphonic suite No. 2 for bassoon and cello). Polish composer Grażyna Bacewicz (1909–1969) was writing for cello in the mid 20th century with Concerto No. 1 for Cello and Orchestra (1951), Concerto No. 2 for Cello and Orchestra (1963) and in 1964 composed her Quartet for four cellos. The cello's versatility made it popular with many male composers in this era as well, such as Sergei Prokofiev, Dmitri Shostakovich, Benjamin Britten, György Ligeti, Witold Lutoslawski and Henri Dutilleux.
