A "Rhythm Section" is a group of musicians in a band or orchestra responsible for maintaining the tempo and providing the harmonic foundation of a piece of music. Typically, this section includes instruments like the drums, bass guitar, and sometimes piano or guitar. Their role is crucial in creating a steady beat and supporting the melody played by other instruments or vocalists. In various music genres, the rhythm section adapts to fit the style. For example, in jazz, the rhythm section often includes a double bass and piano, while in rock, it usually features an electric guitar and a drum kit. This section helps to drive the music forward and keeps the overall sound cohesive.
