Basso continuo in the context of "Keyboard section"

A musical ensemble, also known as a music group, musical group, or a band is a group of people who perform instrumental and/or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instrumentalists, such as the jazz quartet or the orchestra. Other music ensembles consist solely of singers, such as choirs and doo-wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers. In classical music, trios or quartets either blend the sounds of musical instrument families (such as piano, strings, and wind instruments) or group instruments from the same instrument family, such as string ensembles (e.g., string quartet) or wind ensembles (e.g., wind quintet). Some ensembles blend the sounds of a variety of instrument families, such as the orchestra, which uses a string section, brass instruments, woodwinds, and percussion instruments, or the concert band, which uses brass, woodwinds, and percussion. In jazz ensembles or combos, the instruments typically include wind instruments (one or more saxophones, trumpets, etc.), one or two chordal "comping" instruments (electric guitar, acoustic guitar, piano, or Hammond organ), a bass instrument (bass guitar or double bass), and a drummer or percussionist. Jazz ensembles may be solely instrumental, or they may consist of a group of instruments accompanying one or more singers. In rock and pop ensembles, usually called rock bands or pop bands, there are usually guitars and keyboards (piano, electric piano, Hammond organ, synthesizer, etc.), one or more singers, and a rhythm section made up of a bass guitar and drum kit.

Music ensembles typically have a leader. In jazz bands, rock and pop groups, and similar ensembles, this is the band leader. In classical music, orchestras, concert bands, and choirs are led by a conductor. In orchestra, the concertmaster (principal first violin player) is the instrumentalist leader of the orchestra. In orchestras, the individual sections also have leaders, typically called the "principal" of the section (e.g., the leader of the viola section is called the "principal viola"). Conductors are also used in jazz big bands and in some very large rock or pop ensembles (e.g., a rock concert that includes a string section, a horn section, and a choir that accompanies a rock band's performance).

Accompaniment is the musical part which provides the rhythmic and/or harmonic support for the melody or main themes of a song or instrumental piece. There are many different styles and types of accompaniment in different genres and styles of music. In homophonic music, the main accompaniment approach used in popular music, a clear vocal melody is supported by subordinate chords. In popular music and traditional music, the accompaniment parts typically provide the "beat" for the music and outline the chord progression of the song or instrumental piece.

The accompaniment for a vocal melody or instrumental solo can be played by a single musician playing an instrument such as piano, pipe organ, or guitar. While any instrument can in theory be used as an accompaniment instrument, keyboard and guitar-family instruments tend to be used if there is only a single instrument, as these instruments can play chords and basslines simultaneously (chords and a bassline are easier to play simultaneously on keyboard instruments, but a fingerpicking guitarist can play chords and a bassline simultaneously on guitar). A solo singer can accompany themself by playing guitar or piano while they sing, and in some rare cases, a solo singer can even accompany themself just using their voice and body (e.g., Bobby McFerrin).

Recitative (/ˌrɛsɪtəˈtiːv/, also known by its Italian name recitativo ([retʃitaˈtiːvo]) is a style of delivery (much used in operas, oratorios, and cantatas) in which a singer is allowed to adopt the rhythms and delivery of ordinary speech. Recitative does not repeat lines as formally composed songs do. It resembles sung ordinary speech more than a formal musical composition.

Recitative can be distinguished on a continuum from more speech-like to more musically sung, with more sustained melodic lines. The mostly syllabic recitativo secco ("dry", accompanied only by continuo, typically cello and harpsichord) is at one end of the spectrum, through recitativo accompagnato (using orchestra), the more melismatic arioso, and finally the full-blown aria or ensemble, where the pulse is entirely governed by the music. Secco recitatives can be more improvisatory and free for the singer, since the accompaniment is so sparse; in contrast, when recitative is accompanied by orchestra, the singer must perform in a more structured way.

In music, a solo (Italian for 'alone') is a piece or a section of a piece played or sung featuring a single performer, who may be performing completely alone or supported by an accompanying instrument such as a piano or organ, a continuo group (in Baroque music), or the rest of a choir, orchestra, band, or other ensemble. Performing a solo is "to solo", and the performer is known as a soloist.

The plural is soli or the anglicised form solos. In some contexts these are interchangeable, but soli tends to be restricted to classical music, and mostly either the solo performers or the solo passages in a single piece. 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.

Renaissance music is traditionally understood to cover European music of the 15th and 16th centuries, later than the Renaissance era as it is understood in other disciplines. Rather than starting from the early 14th-century ars nova, the Trecento music was treated by musicology as a coda to medieval music and the new era dated from the rise of triadic harmony and the spread of the contenance angloise style from the British Isles to the Burgundian School. A convenient watershed for its end is the adoption of basso continuo at the beginning of the Baroque period.

The period may be roughly subdivided, with an early period corresponding to the career of Guillaume Du Fay (c. 1397–1474) and the cultivation of cantilena style, a middle dominated by Franco-Flemish School and the four-part textures favored by Johannes Ockeghem (1410s or '20s–1497) and Josquin des Prez (late 1450s–1521), and culminating during the Counter-Reformation in the florid counterpoint of Palestrina (c. 1525–1594) and the Roman School.

Baroque music (UK: /bəˈrɒk/ or US: /bəˈroʊk/) refers to the period or dominant style of Western classical music composed from about 1600 to 1750. The Baroque style followed the Renaissance period, and was followed in turn by the Classical period after a short transition (the galant style). The Baroque period is divided into three major phases: early, middle, and late. Overlapping in time, they are conventionally dated from 1580 to 1650, from 1630 to 1700, and from 1680 to 1750. Baroque music forms a major portion of the "classical music" canon, and continues to be widely studied, performed, and listened to. The term "baroque" comes from the Portuguese word barroco, meaning "misshapen pearl". Key composers of the Baroque era include Johann Sebastian Bach, George Frideric Handel, Henry Purcell, Antonio Vivaldi, Georg Philipp Telemann, Domenico Scarlatti, Claudio Monteverdi, Girolamo Frescobaldi, Alessandro Scarlatti, Jean-Baptiste Lully, Jean-Philippe Rameau, Arcangelo Corelli, François Couperin, Heinrich Schütz, Dieterich Buxtehude, and Heinrich Ignaz Franz Biber.

The Baroque saw the formalization of common-practice tonality, an approach to writing music in which a song or piece is written in a particular key; this type of harmony has continued to be used extensively in Western classical and popular music. During the Baroque era, professional musicians were expected to be accomplished improvisers of both solo melodic lines and accompaniment parts. Baroque concerts were typically accompanied by a basso continuo group (comprising chord-playing instrumentalists such as harpsichordists and lute players improvising chords from a figured bass part) while a group of bass instruments—viol, cello, double bass—played the bassline. A characteristic Baroque form was the dance suite. While the pieces in a dance suite were inspired by actual dance music, dance suites were designed purely for listening, not for accompanying dancers.

The theorbo is a plucked string instrument of the lute family, with an extended neck that houses the second pegbox. Like a lute, a theorbo has a curved-back sound box with a flat top, typically with one or three sound holes decorated with rosettes. As with the lute, the player plucks or strums the strings with the right hand while "fretting" (pressing down) the strings with the left hand.

The theorbo is related to the liuto attiorbato, the French théorbe des pièces, the archlute, the German baroque lute, and the angélique (or angelica). A theorbo differs from a regular lute in its re-entrant tuning in which the first two strings are tuned an octave lower. The theorbo was used during the Baroque music era (1600–1750) to play basso continuo accompaniment parts (as part of the basso continuo group, which often included harpsichord, pipe organ and bass instruments), and also as a solo instrument. It has a range similar to that of cello.
