A power trio is a rock and roll band format having a lineup of electric guitar, bass guitar and drum kit (drums and cymbals), leaving out the second rhythm guitar or keyboard instrument that are used in other rock music bands that are quartets and quintets. Larger rock bands use one or more additional rhythm section to fill out the sound with chords and harmony parts.


Most power trios in hard rock and heavy metal music use the electric guitar player in two roles; during much of the song, they play rhythm guitar, playing the chord progression for the song and performing the song's important riffs, and then switching to a lead guitar role during the guitar solo. While one or more band members typically sing while they play their instruments, power trios in hard rock and heavy metal music generally emphasize instrumental performance and overall sonic impact over vocals and lyrics. [1] An example of a power trio is Motörhead, which consisted of a bassist, guitarist and drummer, with Lemmy, the bass guitarist, singing lead vocals simultaneously while he played bass. Although four-piece bands such as The Who or Led Zeppelin may function instrumentally as a power trio, with three instrumentalists and a lead singer, or front man, these bands are not usually considered as power trios.


The rise of the power trio in the 1960s was made possible in part by developments in amplifier technology that greatly enhanced the volume of the electric guitar and bass. Particularly, the popularization of the electric bass guitar defined the bottom end and filled in the gaps. Since the amplified bass could also now be louder, the rest of the band could also play at higher volumes, without fear of being unable to hear the bass. This allowed a three-person band to have the same sonic impact as a large band but left far more room for improvisation and creativity, unencumbered by the need for detailed arrangements. As with the organ trio, a 1960s-era soul jazz group centered on the amplified Hammond organ, a three-piece group could fill a large bar or club with a big sound for a much lower price than a large rock and roll band. A power trio, at least in its blues rock incarnation, is also generally held to have developed out of Chicago-style blues bands such as Muddy Waters' trio.

In addition to technological improvements, another impetus for the rise of the power trio was the virtuosity of guitarists such as Eric Clapton, Jimi Hendrix, and Rory Gallagher, who could essentially cover both the rhythm guitar and lead guitar roles in a live performance. In 1964, Frank Zappa played guitar in a power trio the Muthers, with Paul Woods on bass and Les Papp on drums. [2] In 1966, the prototypical blues-rock power trio Cream [3] was formed, consisting of Eric Clapton on guitar/vocals, Jack Bruce on bass/vocals, and Ginger Baker on drums. Other influential 1960s-era blues rock/hard rock power trio bands were the Jimi Hendrix Experience, [4] Blue Cheer, Grand Funk Railroad, [5] the James Gang featuring Joe Walsh, and Taste. [6]

Well-known 1970s-era power trios include the Canadian progressive rock groups Rush and Triumph [7] , the American band ZZ Top, [8] the British heavy metal band Motörhead, and Robin Trower. Emerson, Lake & Palmer (as well as its offshoot Emerson, Lake & Powell), while replacing the guitarist by a keyboardist, is usually considered as a power trio, [9] [10] as Keith Emerson fulfilled the rhythm and lead playing on the keyboards that would usually fall on the guitarist, while bassist (and occasional guitarist) Greg Lake was the vocalist. In 1968, the power trio Manal was formed in Argentina, and were the first group that composed blues music in Spanish. [11] [12]

After the 1970s, the phrase "power trio" was applied to the new wave group the Police, [13] grunge band Nirvana, alternative rock band Hüsker Dü, mod revivalists the Jam, hard rock/progressive metal band King's X, progressive rock band Rush, post-grunge band Silverchair, alternative bands the Presidents of the United States of America, Goo Goo Dolls, Primus, Everclear, Muse, and Eve 6, pop punk bands such as Green Day, Blink-182, Alkaline Trio and MxPx, and Argentine rock bands like Soda Stereo, Divididos and From Power Project. Also, by the 1990s, rock trios began to form around different instrumentation, from the band Morphine, featuring a baritone saxophone instead of an electric guitar, to Ben Folds Five's replacing the guitar with various keyboards, principally the piano.

Funk is a music genre that originated in African-American communities in the mid-1960s when musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and rhythm and blues (R&B). Funk de-emphasizes melody and chord progressions and focuses on a strong rhythmic groove of a bassline played by an electric bassist and a drum part played by a drummer, often at slower tempos than other popular music. Like much of African-inspired music, funk typically consists of a complex groove with rhythm instruments playing interlocking grooves that created a "hypnotic" and "danceable feel". Funk uses the same richly colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths and thirteenths.

Musical ensemble Group of people who perform instrumental and/or vocal music, with the ensemble typically known by a distinct name

A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo and one or more singers. 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. Some ensembles blend the sounds of a variety of instrument families, such as the orchestra, which uses a string section, brass instruments, woodwinds and percussion instruments, or the concert band, which uses brass, woodwinds and percussion.

Rhythm guitar Guitar used to provide rhythm

In music performances, rhythm guitar is a technique and role that performs a combination of two functions: to provide all or part of the rhythmic pulse in conjunction with other instruments from the rhythm section ; and to provide all or part of the harmony, i.e. the chords from a song's chord progression, where a chord is a group of notes played together. Therefore, the basic technique of rhythm guitar is to hold down a series of chords with the fretting hand while strumming or fingerpicking rhythmically with the other hand. More developed rhythm techniques include arpeggios, damping, riffs, chord solos, and complex strums.

Hard rock is a loosely defined subgenre of rock music typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, and drums, sometimes accompanied with keyboards. It began in the mid-1960s with the garage, psychedelic and blues rock movements. Hard rock developed into a major form of popular music in the 1970s, with bands such as the Who, Boston, Led Zeppelin, Deep Purple, Aerosmith, Kiss, Queen, AC/DC and Van Halen. During the 1980s, some hard-rock bands moved away from their hard-rock roots and more towards pop rock. Established bands made a comeback in the mid-1980s and hard rock reached a commercial peak in the 1980s, with glam metal bands like Bon Jovi, and Def Leppard and the rawer sounds of Guns N' Roses, which followed up with great success in the later part of that decade.

Instrumental rock is rock music that emphasizes musical instruments and features very little or no singing. Examples of instrumental rock can be found in practically every subgenre of rock, often from musicians who specialize in the style. Instrumental rock was most popular from the mid-1950s to mid-1960s, with artists such as Bill Doggett Combo, The Fireballs, The Shadows, The Ventures, Johnny and the Hurricanes and The Spotnicks. Surf music had many instrumental songs. Many instrumental hits came from the R&B world. Funk and disco produced several instrumental hit singles during the 1970s. The Allman Brothers Band feature several instrumentals. Jeff Beck also recorded two instrumental albums in the 1970s. Progressive rock and art rock performers of the 1960s and 1970s did many virtuosic instrumental performances.

Blues rock is a fusion genre combining elements of blues and rock. It is mostly an electric ensemble-style music with instrumentation similar to electric blues and rock: electric guitar, electric bass guitar, and drums, sometimes with keyboards and harmonica. From its beginnings in the early to mid-1960s, blues rock has gone through several stylistic shifts and along the way it inspired and influenced hard rock, Southern rock, and early heavy metal. Blues rock continues to be an influence in the 2020s, with performances and recordings by popular artists.

Guitar solo

A guitar solo is a melodic passage, instrumental section, or entire piece of music written for a classical guitar, electric guitar or an acoustic guitar. In 20th and 21st century traditional music and popular music such as blues, swing, jazz, jazz fusion, rock and metal, guitar solos often contain virtuoso techniques and varying degrees of improvisation. Guitar solos on classical guitar, which are typically written in musical notation, are also used in classical music forms such as chamber music and concertos.

Rhythm section group of musicians within a music ensemble or band who provide the underlying rhythm, harmony and beat for the rest of the band

A rhythm section is a group of musicians within a music ensemble or band that provides the underlying rhythm, harmony and pulse of the accompaniment, providing a rhythmic and harmonic reference and "beat" for the rest of the band. The rhythm section is often contrasted with the roles of other musicians in the band, such as the lead guitarist or lead vocals whose primary job is to carry the melody.

An organ trio is a form of jazz ensemble consisting of three musicians; a Hammond organ player, a drummer, and either a jazz guitarist or a saxophone player. In some cases the saxophonist will join a trio which consists of an organist, guitarist, and drummer, making it a quartet. Organ trios were a popular type of jazz ensemble for club and bar settings in the 1950s and 1960s, performing a blues-based style of jazz that incorporated elements of R&B. The organ trio format was characterized by long improvised solos and an exploration of different musical "moods".

Heavy metal bass heavy metal instrument and associated playing style

Heavy metal bass is the use of the bass guitar in the rock music genres of heavy metal and hard rock. The bassist is part of the rhythm section in a heavy metal band, along with the drummer, rhythm guitarist and, in some bands, a keyboard player. The prominent role of the bass is key to the metal sound, and the interplay of bass and distorted electric guitar is a central element of metal. The bass guitar provides the low-end sound crucial to making the music "heavy". The bass plays a "... more important role in heavy metal than in any other genre of rock."

Heavy metal guitar heavy metal instrument and associated playing style

Heavy metal guitar is the use of highly-amplified electric guitar in heavy metal. Heavy metal guitar playing is rooted in the guitar playing styles developed in 1960s-era blues rock and psychedelic rock, and it uses a massive sound, characterized by highly amplified distortion, extended guitar solos and overall loudness. The electric guitar and the sonic power that it projects through amplification has historically been the key element in heavy metal. The heavy metal guitar sound comes from a combined use of high volumes and heavy distortion.

Band (rock and pop) musical ensemble which performs music

A rock band or pop band is a small musical ensemble that performs rock music, pop music, or a related genre. A four-piece band is the most common configuration in rock and pop music. In the early years, the configuration was typically two guitarists, a bassist, and a drummer. Another common formation is a vocalist who does not play an instrument, electric guitarist, bass guitarist, and a drummer. Instrumentally, these bands can be considered as trios. Sometimes, in addition to electric guitars, electric bass, and drums, also a keyboardist plays.
