Pulse in music refers to the steady, underlying beat or tempo that provides the rhythmic foundation for a musical piece. It defines the speed and timing of the music, and musicians use it as a reference to maintain the music's forward motion and synchronize their performances.
The pulse is often generated by the rhythmic pulse of the percussion section (e.g., drums) or the tempo set by the conductor in an ensemble. It may be consistent throughout a piece or may undergo slight variations in tempo for expressive purposes. Musicians must accurately feel and adhere to the pulse to ensure rhythmic cohesion and accuracy in the music.
The term "pluse" is not a standard musical term, and it is likely a misspelling or mispronunciation of "pulse."
