Since rhythm sections generally provide the background music for lead instruments and solo singers, rhythm sections are typically not as prominent as a singer or soloist.

Some of the most accomplished rhythm sections have become famous, such as The Band, the E Street Band and Sly Dunbar and Robbie Shakespeare (the latter in

that use rhythm sections, ranging from rock to country to jazz, the rhythm section members are expected to be able to improvise (make up) their parts or prepare their own parts for a given song by listening to the CD at home. Once the bassist and chord-playing instruments are provided with the chord progression on a lead sheet (in which chords are typically named using the root note of the chord and its quality; e.g., C Major, d minor, G7, etc.), they are expected to be able to improvise or prepare a bass line and chord voicings, respectively, that suit the style of the song. In each style of music, there are different musical approaches and styles that rhythm section members are expected to use. For example, in a country music song, the guitarist will be expected to be able to perform a chord progression using an intricate fingerpicking style; in a heavy metal song, the guitarist will be expected to play power chords and complex, precise rhythmic patterns; in a

Drummers and percussionists are expected to be able to improvise or prepare rhythm parts that suit the style of a given song. In some cases, an arranger, orchestrator or

It is rare in jazz or rock for chords to be written out in music notation; the arranger or songwriter typically writes the chord symbol and expects the guitarist to improvise the appropriate chord voicing.


Other roles

Rhythm section members may be expected to sing backup vocals or harmony parts in some styles of music. In some styles of music, notably 2010s-era pop, hip hop music and funk, rhythm section members may be required to perform a rhythmic dance routine, which may range from a simple body movement to a complex dance choreography that requires significant dance skills.

, during the 1980s, there was some crossover between the roles played by electronic keyboards and electric guitar. Even though electronic keyboards or organs were the standard instruments used to create sustained "pads" of sound (e.g., held backing chords) for ballads, with the introduction of digital delay pedals and other modern effects, electric guitars could produce similar "pads" or " walls of sound". The Edge, the guitarist from the rock band U2, often used digital delay and reverb-drenched electric guitar arpeggios (chords played one note after the other) to create a shimmering, sustained "pad" for the group. These arpeggio pads created a sustained sound that was similar to the sound of an electronic keyboard. By the late 1980s, the price of digital effects pedals dropped, making these effects units available to the general public. During the 1980s era, rhythm sections in some styles of pop took an increasing turn towards electronic instruments. A 1980s-era dance pop band might be backed up by a rhythm section of a

In the 1980s and 1990s, the roots rock scene went in the opposite direction from dance pop; roots rock favoured traditional instruments in the rhythm section such as acoustic piano, acoustic guitar, mandolin, pedal steel guitar, acoustic bass guitar and upright bass. Another 1980s-era trend that helped revive interest in acoustic instruments was the " MTV Unplugged" style of performances, in which a rock band performs with acoustic instruments, including acoustic guitars and an acoustic bass guitar.

foundation with a bassline. The types of basslines performed by the bass guitarist vary widely from one style of music to another. Despite all of the differences in the styles of bassline in most styles of popular music, the bass guitarist fulfills a similar role: anchoring the harmonic framework (often by emphasizing the roots of the chord progression) and laying down the beat (in collaboration with the drummer). The importance of the bass guitarist and the bass line varies in different styles of music. In some pop styles, such as 1980s-era pop and musical theater, the bass sometimes plays a relatively simple part, and the music forefronts the vocals and melody instruments. In contrast, in

and jazz fusion, the drummer may not play the strict "timekeeping" role that is associated with drums in pop music. Instead, the drums may be used more to create textured polyrhythmic soundscapes. In this type of situation, the main pulse is often provided by the bass player rather than the drummer. The rhythm section members sometimes break out of their accompaniment role when they are asked to perform keyboard solos, bass breaks, or drum solos. In genres such as

Manzarek, guitarist Robby Krieger, and drummer John Densmore would act as an organ trio with the addition of singer Jim Morrison.

Other variants

Not all rhythm sections follow the standard model of drummer-bassist-chordal instrument. Some bands have no drummer. In bands without a drummer, one or more instruments from the rhythm section often play in styles that replace the drum kit role—that is laying down the beat and backbeat. Traditional bluegrass bands typically do not have a drummer. In bluegrass bands, the timekeeping role is shared between several instruments: the upright bass generally plays the on-beats while the mandolin plays chop chords on the off-beats, with the banjo also keeping a steady eighth note rhythm. This distributed nature allows for rhythmic continuity while players take turns highlighting the melody. In funk-oriented groups that do not have a drummer, the electric bass player may take over some of the drummer's role by using slap bass. With slap bass, the bassist slaps the low strings to create a strong "thump" (similar to the bass drum's role) and "snaps" or "pops" the high strings to create a percussive effect (the latter takes over some of the role played by the hi-hat cymbals). In some bands, there may be no bass player—the basslines may be played by the piano player, synth player, or guitarist. Using a guitar player to provide basslines is particularly effective if a guitar player has a seven-string guitar with a low "B" string. Some jazz duos consist of a singer accompanied by a single piano player. In these duos, the jazz piano player has a challenging task; they have to provide all of the rhythmic and harmonic foundation that would normally be provided by a full rhythm section. A jazz pianist accompanying a singer in a duo needs to play a deep bassline, chords, and fill-in melody lines while the singer is performing. The pianist often improvises an instrumental solo in between vocal melodies. Rarely, a jazz vocalist may perform in a duo with a double bass player. In this duo setting, the bass player may have to use less commonly-used bass techniques to fill out the sound, such as occasionally playing two or three-note double stops (to recreate the chord-playing role normally filled by a guitar or piano) or using percussive slaps on the fingerboard (to recreate some of the percussive elements provided by a drummer). The Canadian bassist Michel Donato has performed in a duo with singer Karen Young, and the pair released several albums in the 1980s and 1990s.
