Beat: The basic beat in disco music is usually a four-on-the-floor pattern, where the bass drum hits on each beat and the snare drum hits on beats two and four.
Rhythm: Disco is characterized by a syncopated rhythm, where the emphasis is on the off-beats. This creates a sense of movement and energy in the music. The hi-hats and other percussion instruments often play intricate patterns that add to the rhythmic complexity.
Overall, the combination of tempo, beat, and rhythm creates a lively, dance-oriented feel that is characteristic of disco music.
