Musical Ensemble Size and Structure

A musical ensemble refers to a group of musicians that performs as a unit. Whether it’s two musicians or a hundred, the group works as one to produce a cohesive piece. If you are looking to make music with other individuals, it’s important to learn the names of different musical groups.

Types of Musical Ensembles

Ensembles can exclusively comprise singers, instrumentalists, or a combination of both. We can categorize musical ensembles into two main groups; small ensembles and large ensembles.

Small Ensembles

These are musical groups of two to ten people. We’ll define each in detail below.

i. Duet

Also known as a musical duo, this is a group of two musicians performing a piece together. Each of the two musicians offers critical importance to the composition which is why duets usually feature two singers or pianists.

Instead of harmonizing each other’s vocals, musicians in a duet each get a solo in the piece. When two pianists are performing on the same piano, the music is called a piano duet. On the other hand, if the pianists are playing on separate instruments, it’s called a piano duo.

Duets have classical origins, finding a place in operas as early as the 17th century. However, they also have a place in modern pop music. Duets usually feature a conversation-type of music that shows the perspectives of the first and second musicians.

ii. Trio

When a musical piece requires three people to perform, it’s called a trio. It could be three instrumentalists or vocalists performing a common piece. Dating back to the 17th and 18th centuries, trios typically involved two musical instruments and a continuo group. Today, there are different ways to make a trio by combining different instruments.

Here are some common instrumental trios:

  • Piano trios – comprising a piano, violin, and cello
  • Organ trio – comprising a Hammond organ, jazz guitar, and drum
  • Harmonica trio – comprising bass, chord, and chromatic harmonicas.

iii. Quartet

An ensemble of four musicians is called a quartet. You can easily see this type of group in classical music through a combination of four instruments. A good example of this ensemble is a string quartet in chamber music.

This quartet usually has a viola, a cello, and two violins. The musicians play the instruments to mirror four registers of the vocal range including soprano, alto, tenor, and bass.

Piano quartets are another variation of classical music. These usually feature a piano, cello, violin, and viola. Famous composers like Beethoven and Mozart have quartet compositions of this nature.

Wind quartets are another category. They could involve a combination of four wind instruments or a wind instrument, viola, violin, and cello. Instrumentals aside, you can also make a quartet ensemble of vocalists. This ensemble could come in a variety of combinations like the four vocal registers, male groups, female groups, or a mix of male and female voices.

iv. Quintet

If you add an extra instrument to a string quartet, you end up with a quintet. This ensemble features five musicians each playing an instrument in the same musical composition. A wind quintet typically includes a flute, horn, bassoon, oboe, and clarinet.

Another classical variation of this ensemble is the brass quintet which has a tuba, trombone, horn, and two trumpets.

v. Sextet

Also known as a hexad, this ensemble comprises six individuals. It could be a composition for six-string instruments which is called a string sextet. It could also feature a piano and a combination of other instruments, earning the name piano sextet. Rock and jazz bands also have sextets of six instrument players.

vi. Septet

One of the popular jazz ensembles is the septet. This group of seven instrumentalists usually features a string bass, drum set, and several other instruments.

vii. Octet

An octet is a group of eight musicians and it is one of the largest chamber music ensembles. Octets can exist in different forms including string octets, wind octets, or a combination of both. In classical music, octets can be formed by mixing two quartets into a single unit. Octets also exist in jazz and include eight instrumentalists with a variety of instruments.

viii. Nonet

This ensemble comprises nine musicians and could have various instruments for a classical music setting. Nonets could also feature the same type of instrument which is how we have string nonets and wind nonets.

ix. Decet

A decet or decimette is a musical group of ten people. This ensemble doesn’t have a defined standard for musical instruments.

x. Undecet

This is a group of eleven musicians. It’s not a common ensemble that you can easily find today.

xi. Duodecet

A duodenal is a musical ensemble of 12 members. A jazz band of twelve is called a twelvetet.

Large Ensembles

Now that we’ve covered small ensembles, let’s look at musical groupings that fall under large ensembles.

i. Chamber Orchestra

A chamber orchestra is an ensemble of about 12 to 40 classical-playing musicians. The instruments will come in groups, each used in a specific part of the composition. Usually, this ensemble can do without a conductor, so the musicians need to be highly skilled and dynamic to play a piece in unison.

In the 17th century, European royalty and members of the upper classes of society used to hire musicians to play classical music in a chamber. This was a means of entertaining house guests who were the audience of the performers. That is how the term “chamber music” came to be.

ii. Symphony Orchestra

Symphony orchestras are much larger than chamber orchestras. With up to 100 musicians, symphony orchestras feature many types of instruments including brass, bass, string, wind, and percussion instruments. Usually, there’ll be more than one instrument playing each part of the composition.

Another way to differentiate a chamber orchestra and a symphony are how it’s led. A symphony orchestra usually features a conductor who directs the music with body language and gestures.

iii. Concert Bands

This ensemble features about 80 to 100 musicians playing percussion, woodwind, and brass instruments. They differ from marching bands because they perform in a concert hall rather than on the move. Unlike orchestras, this ensemble doesn’t feature string instruments.

There are many names for concert bands including wind orchestras, wind ensembles, and symphonic bands. The band leaders of concert bands are called concertmasters.

iv. Marching Bands

Similar to concert bands, marching bands also use brass, percussion, and woodwind instruments. These musicians perform while marching during parades in a professional setting, sports events, and band-marching competitions.

v. Choir

This ensemble is a body of singers that perform together. A choir can handle anything from classical songs to modern pop music. In most cases, this ensemble will have a conductor who leads the group.
