In music, a solo (from the Italian: solo, meaning alone, even though assolo is now used in Italy when referring to the musical solo) is a piece or a section of a piece played or sung by a single performer. In practice this means a number of different things, depending on the type of music and the context.

The word is also used for the act of performing a solo, and sometimes for the performer (more often a soloist).

The plural is soli or the anglicised form solos. In some context these are interchangeable, but soli tends to be restricted to classical music, and tends to refer to either the solo performers or the solo passages in a single piece: it would not often be used to refer to several pieces that happen to be for single performers. Furthermore, the word soli can be used to refer to a small number of simultaneous parts assigned to single players in an orchestral composition. In the Baroque concerto grosso, the term for such a group of soloists was concertino.

In the Baroque and Classical periods, the word solo was virtually equivalent to sonata, and could refer either to a piece for one melody instrument with (continuo) accompaniment, or to a sonata for an unaccompanied melody instrument, such as Johann Sebastian Bach’s sonatas for violin alone.

Solo or SOLO may refer to:

Music is an art form whose medium is sound and silence. Its common elements are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike; "art of the Muses").

The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music may be classified as a performing art, a fine art, and auditory art. There is also a strong connection between music and mathematics.

To many people in many cultures, music is an important part of their way of life. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound." Musicologist Jean-Jacques Nattiez summarizes the relativist, post-modern viewpoint: "The border between music and noise is always culturally defined—which implies that, even within a single society, this border does not always pass through the same place; in short, there is rarely a consensus ... By all accounts there is no single and intercultural universal concept defining what music might be."

Johann Sebastian Bach (31 March [O.S. 21 March] 1685 – 28 July 1750) was a German composer, organist, harpsichordist, violist, and violinist of the Baroque Period. He enriched many established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach wrote much music, which was revered for its intellectual depth, technical command, and artistic beauty. Many of his works are still known today, such as the Brandenburg Concertos, the Mass in B minor, the Well-Tempered Clavier, and his cantatas, chorales, partitas, passions, and organ works.

Bach was born in Eisenach, Saxe-Eisenach into a very musical family; his father, Johann Ambrosius Bach was the director of the town's musicians, and all of his uncles were professional musicians. His father taught him to play violin and harpsichord, and his brother, Johann Christoph Bach taught him the clavichord, and exposed him to much contemporary music. Bach also sang, and he went to the St Michael's School in Lüneburg, because of his skill in voice. After graduating, he held several musical posts across Germany; he served as Kapellmeister (director of music) to Leopold, Prince of Anhalt-Köthen, Cantor of Thomasschule in Leipzig, and Royal Court Composer to August III. Bach's health and vision declined in 1749, and he died on 28 July 1750. Modern historians believe that his death was caused by a combination of stroke and pneumonia.
