What are the key facts about pulse for music?

Pulse in music refers to the regular, steady beat that underlies a piece of music, serving as a framework for timing and rhythm. It is often perceived as the heartbeat of the music, allowing listeners to feel a sense of movement and structure. Pulses can vary in speed (tempo) and can be organized into rhythmic patterns, which help define the style and feel of a piece. Musicians often use pulse to synchronize their performances and create a cohesive sound.
