A musical group or musical ensemble is an artistic partnership made up of people who play music permanently together. It indicates both the set of roles of the musicians and their concrete grouping, be they professionals or amateurs. In the different fields and musical genres in which a musical group is considered, it is varied in terms of staff, repertoire and function. In the jazz field, a musical group is also defined as a duo or trio, depending on whether it is made up of two or three elements. Furthermore, an instrumental ensemble is made up of instrumentalists, while a vocal ensemble is made up of singers. The terms musical group, musical ensemble, musical ensemble, musical formation and ensemble musical formation are widely used in literature. However, these terms can also refer par excellence only to jazz, rock and pop groups. The words group, together and complex in common language have the same ambivalence. A musical body is instead a band. The term ensemble is also used, to indicate a group of musicians without predominant parts, or a folkloric musical ensemble characteristic of a country, with a generality or specificity in the different meaning of the term in different languages.


The formation of a band depends on the genre of music it has to perform, as each genre has its own characteristic ensembles. When a group of people works on the recording of a song, usually in classical music, the recording takes place directly with the complete ensemble, while in other genres it is possible to record the various tracks (tracks) separately and therefore only one musician can perform different parts; during concerts this is not possible so, if necessary, we resort to the help of session players who play the parts that are not performed by the main components of the ensemble. They are examples of musical ensembles, very different from each other: duos, trios, quartets, quintets, small sections of musicians who play cultured music orchestras, bands, choirs, large groups of singers or instrumentalists from the operatic, band or symphonic repertoire groups, bands, groups of rock and pop music in general of no more than ten musicians jazz bands, jazz combo, jazz ensembles composed of more or less artists

Formations like


The simplest formation in rock (and sub-genres such as hard rock, punk rock and heavy metal) is the power trio: drummer, bassist and guitarist, where at least one of the three is also a singer, usually the guitarist. Generally, the training can consist of: a singer; two guitarists (soloist and rhythmist); a bass player. a drummer. a keyboard player, in more recent times. Sometimes there are more than two guitarists, and one of the instrumentalists can also be an additional voice. Often there are additional instruments, such as organ, synthesizer and sampler, or wind instruments such as sax and trumpet. In any case, bass and drums are essential in any type of group, because they constitute the rhythm section of the ensemble. A typical rock formation can also be used in the genres listed below and in folk, with the addition or replacement of other instruments if necessary.


In a hip hop or rap group (where the band is called a crew) there are generally no instrumentalists, as the music is played with synthesizers and samplers, capable of reproducing all sounds. In concerts, synthesizers or drums are sometimes used.

Jazz and blues

In black music the staff often increases, adding to the group as described above the horn section (from 3 to 5 elements) and the choristers section, as well as easily seeing the coexistence of organ and piano. In jazz in particular, the formation varies according to the eras: from the origins to the swing period (1930-1940) it is the era of the big wind bands, Jazz Orchestra c
