Rhythm guitar is a style of playing that focuses on providing the harmonic and rhythmic foundation for a song. It typically involves strumming chords or playing simple riffs that support the melody. This role is crucial in many genres, including rock, pop, and blues, as it helps to create a solid groove for the music. In a band, the rhythm guitarist works closely with the drummer and bass guitarist to establish the song's tempo and feel. While lead guitarists often take the spotlight with solos, rhythm guitarists are essential for maintaining the overall structure and energy of the performance.
