rock band

Two parts

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 (vocals, chords, bass lines, and percussion or drumming) with trios or quartets. 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 Death From Above 1979, The White Stripes, The Ting Tings and Black Aspirin.

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 used pre-programmed sequencers. Other pop bands from the 1980s which were ostensibly fronted by two performers, such as Wham! 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 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. 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. Providence-based Lightning Bolt is a two-member band. Bassist Brian Gibson augments his playing with delay pedals, pitch shifters, looping devices and other pedals, occasionally creating harmony. Local H, No Age, Warship, and Growing are other prominent two-person experimental rock bands.

Example line-up

• Lead vocals, lead guitar
• Drums

Three parts

Further information: Power trio

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 (sometimes all three members will sing, e.g. Bee Gees). Some well-known power trios are: The Jimi Hendrix Experience, The Police, Nirvana, Rush, Cream, Green Day, Blink-182, 30 Seconds to Mars and Muse (band)

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 (playing synthesizers) such as the progressive rock band Emerson, Lake & Palmer.

Example line-up

• Lead vocals, lead guitar
• Bass guitar, keyboards,
• Drums, percussion

Four parts

The four-piece band is the most common configuration in rock and pop music. Before the development of the electronic keyboard, the configuration was typically two guitarists (one lead guitarist and one rhythm guitarist, with the latter on vocals), a bass player (typically the electric bass guitar) and a drummer (e.g., The Beatles, Foo Fighters, Weezer, Coldplay, The Moderns, Metallica, The Clash , Nickleback, Creedence Clearwater Revival, The Kinks, The Pixies, and The Smashing Pumpkins) Another common formation was a vocalist, electric guitarist, electric bassist and a drummer (e.g.The Who, Led Zeppelin, Red Hot Chili Peppers, Queen, Rage Against the Machine, Black Sabbath, No Doubt, Cheap Trick, U2, Jane's Addiction, L'arc~en~Ciel). Instrumentally, these bands can be considered as trios. In some early rock bands, keyboardists were used, performing on piano (e.g., The Rolling Stones initially used Ian Stewart on piano), The Doors with a guitarist, singer, drummer and keyboardist. Electric pianos (such as the Fender Rhodes), or organ (such as the Hammond organ) (e.g, Pink Floyd).

[edit] Example line-up

• Lead vocals, Lead guitar
• Rhythm guitar or Keyboards
• Bass guitar, backing vocals
• Drums, percussion

Five parts

Five-part bands have existed in rock music since early times. The Beach Boys, The Rolling Stones, Aerosmith, Def Leppard, AC/DC, Oasis, Pearl Jam, Guns N' Roses, Steely Dan, and The Strokes are examples of the common vocalist, lead guitar, rhythm guitar, bass, and drums lineup. An alternative to the five-member lineup replaces the rhythm guitarist with a keyboard–synthesizer player (examples being the bands Bon Jovi, Yes, Fleetwood Mac, Marilyn Manson and Deep Purple, all of which consist of a vocalist, guitarist, bassist, keyboardist, and a drummer) or with a turntablist such as Incubus or Limp Bizkit.

[edit] Example line-up

• Lead vocals
• Lead guitar, backing vocals
• Keyboards or Rhythm Guitar
• Bass guitar, backing vocals
• Drums, percussion

Larger rock ensembles

Larger bands have long been a part of rock and pop music, in part due to the influence of the "singer accompanied with orchestra" model inherited from popular big-band jazz and swing and popularized by Frank Sinatra and Ella Fitzgerald. To create larger ensembles, rock bands often add an additional guitarist (as in Iron Maiden); an additional keyboardist (as in Procol Harum); additional percussionists (as in Latin-rock bands, e.g. Santana); or second drummer (as in The Grateful Dead and The Allman Brothers Band). Stevie Nicks has an extra guitarist, sometimes drummer and three backup singers in her band. Nu metal band Linkin Park fits the rap rock genre with the inclusion of their turntablist & their emcee, who also plays rhythm guitar & keyboards. Slipknot has nine members, including a turntablist and two percussionists who match the drum beat. In other rock bands, particularly those influenced by other genres such as folk, classical, or country, the additional instrumentalists might include a mandolin player, a banjo player, a sitar player, a fiddler/acoustic violinist, an electric violinist, a timpanist, or a pedal steel guitarist. In some of these larger groups (such as The Band), instrumentalists could play multiple instruments, which enabled the ensemble to create a wider variety of instrument combinations. More rarely, rock or pop groups will be accompanied in concerts by a full or partial symphony orchestra, where lush string-orchestra arrangements are used to flesh out the sound of slow ballads. Third-Wave Ska bands may have six to eight pieces including vocals, guitarist(s), a bassist, a drummer, a trumpet, saxophone, and trombone. Other situations occur depending on the genre the band prefers. For instance, the band Incubus has five members, one of them being a DJ. Also, the band Dare to Dream has five members, including Steven M. Cooper. Huey Lewis and the News also had a large rock ensemble, including the members of the News and the separate jazz band Tower of Power on many of their early hits. Another interesting example is Bang Camaro, who have three guitarists, one keyboardist, one bassist, one drummer, and ten to fifteen singers who sing simultaneously. Bluegrass and other music has roots in Irish folk, and some Irish punk bands such as Flogging Molly have multiple members, some of which play the fiddle, banjo, and the accordion. On the extreme, symphonic metal group Haggard at one time had 21 members, being numerous different types of instrumentalists and vocalists, approaching something more reminiscent of a small chamber orchestra.
