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

ensembles. The terms

The Carnival of the Animals'', is called an ''undecet'', and a group of twelve is called a ''
duodecet'' (see
Latin numerical prefixes). A soloist playing unaccompanied (e.g., a pianist playing a solo piano piece or a cellist playing a
Bach suite for unaccompanied cello) is not an ensemble because it only contains one musician.

Five parts
The string ''quintet'' is a common type of group. It is similar to the string quartet, but with an additional viola, cello, or more rarely, the addition of a double bass. Terms such as "

Mozart's
Clarinet Quintet is similarly a piece written for an ensemble consisting of two violins, a viola, a cello, and a clarinet, the last being the exceptional addition to a "normal" string quartet.
Some other quintets in classical music are the
wind quintet, usually consisting of flute, oboe, clarinet, bassoon, and horn; the
brass quintet, consisting of two trumpets, one horn, a trombone, and a tuba; and the reed quintet, consisting of an oboe, a soprano clarinet, a saxophone, a bass clarinet, and a bassoon.
Six or more instruments

Classical chamber ensembles of six (sextet), seven (septet), or eight musicians (octet) are fairly common; the use of latinate terms for larger groups is rare, except for the nonet (nine musicians). In most cases, a larger classical group is referred to as an orchestra of some type or a concert band. A small orchestra with fifteen to thirty members (violins, violas, four cellos, two or three double basses, and several woodwind or brass instruments) is called a
chamber orchestra. A
sinfonietta usually denotes a somewhat smaller orchestra (though still not a chamber orchestra). Larger orchestras are called
symphony orchestras (see below) or philharmonic orchestras.
A
pops orchestra is an orchestra that mainly performs light classical music (often in abbreviated, simplified arrangements) and orchestral
arrangements and
medleys of popular jazz, music theater, or pop music songs. A
string orchestra has only string instruments, i.e., violins, violas, cellos, and double basses.

An orchestra (; ) is a large instrumental ensemble typical of classical music, which combines instruments from different families. There are typically four main sections of instruments:

is an ensemble usually comprising at least thirty musicians; the number of players is typically between fifty and ninety-five and may exceed one hundred. A symphony orchestra is divided into families of instruments. In the string family, there are sections of violins (I and II), violas, cellos (often eight), and basses (often from six to eight). The standard
woodwind section consists of flutes (one doubling piccolo), oboes (one doubling English horn), soprano clarinets (one doubling bass clarinet), and bassoons (one doubling contrabassoon). The standard
brass section consists of horns, trumpets, trombones, and tuba. The
percussion section includes the
timpani

Classical period music (1750–1820), the percussion parts in orchestral works may only include timpani.
A
wind orchestra or
concert band is a large classical ensemble generally made up of between 40 and 70 musicians from the woodwind, brass, and percussion families, along with the double bass. The concert band has a larger number and variety of wind instruments than the symphony orchestra but does not have a string section (although a single

The woodwind section of a concert band consists of piccolo, flutes, oboes (one doubling English horn), bassoons (one doubling contrabassoon), soprano clarinets (one doubling E clarinet, one doubling alto clarinet), bass clarinets (one doubling contrabass clarinet or contra-alto clarinet), alto saxophones (one doubling soprano saxophone), tenor saxophone, and baritone saxophone. The brass section consists of horns, trumpets or cornets, trombones, euphoniums, and tubas. The percussion section consists of the timpani, bass drum, snare drum, and any other percussion instruments called for in a score (e.g., triangle, glockenspiel, chimes, cymbals, wood blocks, etc.).
Less well known is the large symphonic
accordion orchestra. Typically, it includes between 50 and 100 musicians whose
free-bass instruments are individually re-tuned in order to recreate the full range of orchestral sounds and timbers required for the performance of traditional Western classical music.

Vocal group
A vocal group is a performing ensemble of
vocalists who
sing and harmonize together. The first well-known vocals groups emerged in the 19th century, and the style had reached widespread popularity by the 1940s.
Vocal groups can come in several different forms, including:
Based on genders
*
Boys' choir – vocal group of boys who have yet to begin puberty
*
Boy band – vocal group consisting of (young) males
*
Girl group – vocal group consisting of (young) females
*
Co-ed group – vocal group consisting of both males and females, typically in their teens or early twenties
Based on project type
* Sub-unit – a group that is descended from the main group, with smaller number of members. Usually, all the members are from the main group.
*
Supergroup – a musical group formed with members who are already successful as solo artists or as members of other successful groups.

styles as singers. However, professional women instrumentalists are uncommon in popular music, especially in rock genres such as
heavy metal. "
aying in a band is largely a male homosocial activity, that is, learning to play in a band is largely a peer-based... experience, shaped by existing sex-segregated friendship networks." As well, rock music "...is often defined as a form of male rebellion vis-à-vis female bedroom culture."
In popular music, there has been a gendered "distinction between public (male) and private (female) participation" in music.
"
veral scholars have argued that men exclude women from bands or the bands' rehearsals, recordings, performances, and other social activities."
"Women are mainly regarded as passive and private consumers of allegedly slick, prefabricated – hence, inferior – pop music..., excluding them from participating as high-status rock musicians."
One of the reasons that there are rarely mixed gender bands is that "bands operate as tight-knit units in which homosocial solidarity – social bonds between people of the same sex... – plays a crucial role."
In the 1960s pop music scene, "
nging was sometimes an acceptable pastime for a girl, but playing an instrument...simply wasn't done."
"The rebellion of rock music was largely a male rebellion; the women—often, in the 1950s and '60s, girls in their teens—in rock usually sang songs as personæ utterly dependent on their macho boyfriends..." Philip Auslander says that "Although there were many women in rock by the late 1960s, most performed only as singers, a traditionally feminine position in popular music." Though some women played instruments in American
all-female garage rock bands, none of these bands achieved more than regional success. So they "did not provide viable templates for women's on-going participation in rock".
[
] About the gender composition of
heavy metal bands, it has been said that "
avy metal performers are almost exclusively male"
"...
least until the mid-1980s" apart from "...exceptions such as
Girlschool".
However, "...now
n the 2010smaybe more than ever–strong metal women have put up their dukes and got down to it," "carv
ngout a considerable place for
hemelves".
When
Suzi Quatro emerged in 1973, "no other prominent female musician worked in rock simultaneously as a singer, instrumentalist, songwriter, and bandleader."
According to Auslander, she was "kicking down the male door in rock and roll and proving that a female ''musician'' ... and this is a point I am extremely concerned about ... could play as well if not better than the boys".
