Sextet in the context of "Son (music)"

A number opera (Italian: opera a numeri; German: Nummeroper; French: opéra à numéros) is an opera consisting of individual pieces of music ('numbers') which can be easily extracted from the larger work. They may be numbered consecutively in the score, and may be interspersed with recitative or spoken dialogue. Opera numbers may be arias, but also ensemble pieces, such as duets, trios, quartets, quintets, sextets or choruses. They may also be ballets and instrumental pieces, such as marches, sinfonias, or intermezzi. The number opera format was standard until the mid-19th century and most opera genres, including opera seria, opera buffa, opéra comique, ballad opera, Singspiel, and grand opera, were constructed in this fashion.

The replacement of numbers with more continuous music began in operas by Jommelli, Traetta, Gluck, and especially Mozart, whose late operas Le Nozze di Figaro and Don Giovanni contain several segments in which different numbers are unified by bridge passages to form a musical whole. This trend became even more striking in the operas of the German composers Beethoven, Weber, and Meyerbeer, while their Italian and French contemporaries Rossini, Donizetti, Bellini, and Auber retained the number opera style.

Son cubano (Spanish: [ˌsoŋ kuˈβano]) is a genre of music and dance that originated in the highlands of eastern Cuba during the late 19th century. It is a syncretic genre that blends elements of Spanish and African origin. Among its fundamental Hispanic components are the vocal style, lyrical metre and the primacy of the tres, derived from the Spanish guitar. On the other hand, its characteristic clave rhythm, call and response structure and percussion section (bongo, maracas, etc.) are all rooted in traditions of Bantu origin.

Around 1909 the son reached Havana, where the first recordings were made in 1917. This marked the start of its expansion throughout the island, becoming Cuba's most popular and influential genre. While early groups had between three and five members, during the 1920s the sexteto (sextet) became the genre's primary format. By the 1930s, many bands had incorporated a trumpet, becoming septetos, and in the 1940s a larger type of ensemble featuring congas and piano became the norm: the conjunto. The son became one of the main ingredients in the jam sessions known as descargas that flourished during the 1950s.

Kind of Blue is a studio album by American jazz musician Miles Davis, released on August 17, 1959, by Columbia Records. For this album, Davis led a sextet featuring saxophonists John Coltrane and Julian "Cannonball" Adderley, pianist Bill Evans, bassist Paul Chambers, and drummer Jimmy Cobb, with new band pianist Wynton Kelly replacing Evans on "Freddie Freeloader". The album was recorded at Columbia's 30th Street Studio in New York City in two sessions on March 2 and April 22, 1959.

Influenced in part by Evans, who had been a member of the ensemble in 1958 and was called back for this album, Davis departed further from his early hard bop style in favor of greater experimentation with musical modes, as on the title track of his previous album, Milestones (1958). Basing Kind of Blue entirely on modality, Davis gave each performer a set of scales that encompassed the parameters of their improvisation and style and consequently more creative freedom with melodies; Coltrane later expanded on this modal approach in his own solo career.

Affabre Concinui, also known as Affabre – The Chamber Singers, are a Polish a cappella vocal ensemble (sextet) founded in 1983 by alumni of two famous Polish choirs: Poznań Boys' Choir and Poznań Nightingales, inspired by the British ensemble The King's Singers. The name of the ensemble (Affabre Concinui) means in Latin "perfectly attuned" or "ideally harmonized", which is an artistic credo of the group. They quickly gained renown in Poland and many other countries.
