• B. A fixed pulse
• C. A sequence of chords
• D. A melodic contour

Answer: (A)

Rhythm is the organized movement through time in music. It’s about when notes start, how long they last, and how those durations build patterns within the underlying beat and tempo. The pulse or beat gives a steady timing, but rhythm goes beyond just the pulse by shaping accents, durations, and rests so a groove or feel emerges. That’s why this concept best matches the idea of rhythm as the timing architecture of a musical piece. The idea of a fixed pulse describes only the ongoing beat, not how the notes themselves are timed. A sequence of chords points to harmony, and a melodic contour points to the shape of a tune, not the timing structure. In rock, rhythm drives the groove—drums and bass lock to the pulse while the exact timing of notes creates the feel of the song.
