Can you describe rhythm in music and explain its importance in creating a cohesive musical composition?

Rhythm in music refers to the pattern of beats and timing of notes in a piece. It is like the heartbeat of a song, providing structure and flow. Rhythm helps musicians stay in sync and creates a sense of unity in the music. It is crucial in creating a cohesive musical composition because it gives the music a sense of groove and helps listeners connect with the song on a deeper level.
