A musical ensemble also known as a music group is a group of people who perform instrumental or vocal music, typically known by a distinct name. In classical music, trios or quartets either blend the sounds of musical instrument families or group together instruments from the same instrument family, such as string ensembles or wind ensembles. In jazz ensembles, the instruments typically include wind instruments (one or more saxophones, trumpets, etc.), one or two chordal "comping" instruments (electric guitar, piano, or organ), a bass instrument (electric bass guitar or double bass), and a drummer or percussionist. In rock ensembles, usually called rock bands, there are usually guitars and keyboards (piano, electric piano, Hammond organ, synthesizer, etc.) and a rhythm section composed of a bass guitar and drum kit.
In Western classical music, smaller ensembles are called chamber music ensembles. The terms duet, trio, quartet, quintet, sextet, septet, octet, nonet and dectet describe groups of two up to ten musicians, respectively. A group of eleven musicians, such as found in The Carnival of the Animals, is called either a hendectet or an undectet. A solo isn't an ensemble because it only contains one musician.
A string quartet usually consists of two violins, a viola and a cello. An upper string quartet features two violins and two violas. A lower string quartet features 1 viola, 2 cellos and a double bass.
A woodwind quartet usually features a flute, an oboe, a clarinet and a bassoon. A brass quartet features 2 trumpets, a trombone and a tuba. A wind quartet features a horn, a flute, an oboe and a bassoon. A lower wind quartet features a tuba, a bassoon, a bass clarinet and a trombone.
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 "piano quintet" or "clarinet quintet" frequently refer to a string quartet plus a 5th instrument. Mozart's Clarinet Quintet is similarly a piece written for an ensemble consisting of 2 violins, a viola, a cello and a clarinet, the last being the exceptional addition to a "normal" string quartet.
Other common groupings in classical music are the woodwind quintet, usually consisting of flute, oboe, clarinet, bassoon and horn and the brass quintet, consisting of two trumpets, one french horn, a trombone and a tuba.
Classical chamber ensembles of six, seven (septet), or eight musicians (octet) are fairly common; use of latinate terms for larger groups is rare. In most cases a larger classical group is referred to as an orchestra of some type. 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. In the American education system, sitting groups are known as wind ensembles or concert bands (to differentiate from marching bands). Music is similar to that of a pops orchestra, orchestrated for woodwinds, brass, and percussion. 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 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.
A symphony orchestra is an ensemble usually comprising at least thirty musicians; the number of players is typically between seventy 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, violas, cellos (often 8), and basses (often from 6 to 8). The winds consist of the woodwind family of instruments (flutes and piccolo, oboes and English horn, clarinets [made up of the Eâ™­ clarinet, clarinet, and bass clarinet], saxophones, and bassoons [often including contrabassoon]) and the brass family (horns, trumpets, trombones, euphonium, baritone horn, and tuba). The percussion family includes the timpani, bass drum, snare drum, and any other percussion instruments called for in a score (e.g., triangle, glockenspiel, chimes, cymbals, wood blocks).
When orchestras are performing baroque music, they may also use a harpsichord or pipe organ, playing the continuo part. When orchestras are performing Romantic-era music (from the 19th century), they may also use harps or unusual instruments such as the wind machine. When orchestras are performing music from the 20th century or the 21st century, occasionally instruments such as electric guitar, theremin, or even an electronic synthesizer may be used.
In jazz, there are several types of trios. One type of jazz trio is formed with a piano player, a bass player and a drummer. Another type of jazz trio that became popular in the 1950s and 1960s is the organ trio, which is composed of a Hammond organ player, a drummer, and a 3rd instrumentalist. In organ trios, the Hammond organ player performs the bass line on the organ bass pedals while simultaneously playing chords or lead lines on the keyboard manuals. Other types of trios include the "drummer-less" trio, which consists of a piano player, a double bassist, and a horn (saxophone or trumpet) or guitar player; and the jazz trio with a horn player (saxophone or trumpet), double bass player, and a drummer. In the latter type of trio, the lack of a chordal instrument means that the horn player and the bassist have to imply the changing harmonies with their improvised lines.
Jazz quartets typically add a horn to one of the jazz trios described above. Slightly larger jazz ensembles, such as quintets (five instruments) or sextets (six instruments) typically add other soloing instruments to the basic quartet formation, such as different types of saxophones (e.g., alto saxophone, tenor saxophone, etc.) or an additional chordal instrument.
The lineup of larger jazz ensembles can vary considerably, depending on the style of jazz being performed. In a 1920s-style dixieland jazz band, a larger ensemble would be formed by adding a banjo player, woodwind instruments, as with the clarinet, or additional horns to one of the smaller groups. In a 1940s-style Swing big band, a larger ensemble is formed by adding "sections" of like instruments, such as a saxophone section and a trumpet section, which perform arranged "horn lines" to accompany the ensemble. In a 1970s-style jazz fusion ensemble, a larger ensemble is often formed by adding additional percussionists or sometimes a saxophone player would "double" or "triple" meaning that they would also be proficient at the clarinet, flute or both. Also by the addition of soloing instruments.
Two-member rock and pop bands are relatively rare, because of the difficulty in providing all of the musical elements which are part of the rock or pop sound. Two-member rock and pop bands typically omit one of these musical elements. In many cases, two-member bands will omit a drummer, since guitars, bass guitars, and keyboards can all be used to provide a rhythmic pulse.
Examples of two-member bands are Japandroids, Ween, The Lightning Strikers, Local H, Pet Shop Boys, Hella, Flight of the Conchords, Death from Above 1979, Francis Xavier, I Set My Friends On Fire, Middle Class Rut, The Pity Party, Little Fish, The White Stripes, Big Business, Two Gallants, Lightning Bolt, The Ting Tings, The Black Box Revelation, Satyricon, The Black Keys, Tenacious D, They Might Be Giants (until 1992), Simon and Garfunkel, Hall & Oates, Johnossi and The Pack A.D.
When electronic sequencers became widely available in the 1980s, this made it easier for two-member bands to add in musical elements that the two band members were not able to perform. Sequencers allowed bands to pre-program some elements of their performance, such as an electronic drum part and a synth-bass line. Two-member pop music bands such as Soft Cell, Blancmange and Yazoo used pre-programmed sequencers. Other pop bands from the 1980s which were ostensibly fronted by two performers, such as Wham!, Eurythmics and Tears for Fears, were not actually two-piece ensembles, because other instrumental musicians were used "behind the scenes" to fill out the sound.
Two-piece bands in rock music are quite rare. However, starting in the 2000s, blues-influenced rock bands such as The White Stripes and The Black Keys utilized a guitar and drums scheme. However, this is predated by the Flat Duo Jets from the '80s. Death from Above 1979 featured a drummer and bass guitarist. Tenacious D is a two-guitar band; One Day as a Lion and The Dresden Dolls both feature a keyboardist and a drummer. The band Welk consists of a two-man psychedelic flute band, with the occasional synthesizer. Two-person bands have grown in popularity in experimental rock music.
The smallest ensemble that is commonly used in rock music is the trio format. In a hard rock or blues-rock band, or heavy metal rock group, a "power trio" format is often used, which consists of an electric guitar player, an electric bass guitar player and a drummer, and typically one or more of these musicians also sing. Some well-known power trios with the guitarist on lead vocals are The Jimi Hendrix Experience, Stevie Ray Vaughan and Double Trouble, Nirvana, the original line-up of Green Day, Violent Femmes, Gov't Mule, The Minutemen, Triumph, Shellac, Sublime, Blink-182, Chevelle, Muse, The Jam, Short Stack, ZZ Top,Agnes Strange, and the original lineup of Wolfmother.
A handful of others with the bassist on vocals include Primus, Motxrhead, The Police, The Melvins, Blue Cheer, Rush, The Presidents of the United States of America, Venom, and Cream.
Some power trios feature two lead vocalists, both of which play their respective instruments. For example, in the band blink-182 vocals are split between bassist Mark Hoppus and guitarist Tom DeLonge, or in the band Dinosaur Jr., guitarist J. Mascis is the primary songwriter and vocalist, but bassist Lou Barlow writes some songs and sings as well.
An alternative to the power trio are organ trios formed with an electric guitarist, a drummer and a keyboardist. Although organ trios are most commonly associated with 1950s and 1960s jazz organ trio groups such as those led by organist Jimmy Smith, there are also organ trios in rock-oriented styles, such as jazz-rock fusion and Grateful Dead-influenced jam bands such as Medeski Martin & Wood. In organ trios, the keyboard player typically plays a Hammond organ or similar instrument, which permits the keyboard player to perform bass lines, chords, and lead lines. A variant of the organ trio are trios formed with an electric bassist, a drummer and an electronic keyboardist such as the progressive rock band Emerson, Lake & Palmer, and Atomic Rooster. Another variation is to have a vocalist, a guitarist and a drummer, an example being Yeah Yeah Yeahs. Another variation is two guitars, a bassist, and a drum machine, examples including Magic Wands and Big Black.
A power trio with the guitarist on lead vocals is a popular record company lineup, as the guitarist and singer will usually be the songwriter. Therefore you only have to present one face to the public, the backing band is easy to house, and the songs will likely stay simple and accessible as the frontman will have to sing and play guitar at the same time.
