Pattern of sound played to the beat.

• A. Beat
• B. Rhythm
• C. Harmony
• D. Chorus

Answer: (B)

Rhythm is the arrangement of sounds in time—the pattern of notes, rests, durations, and accents that unfold as the music moves. When you describe a pattern of sound played to the beat, you’re referring to how those notes line up with the underlying pulse you feel as the beat. The beat is the steady pulse, like a metronome, while rhythm uses that pulse to determine which notes are long or short, where accents fall, and where silences occur. Harmony is about pitches sounding together to form chords, not the timing of individual notes, and a chorus is a repeating section of a song, not the timing pattern itself. So the concept that fits best is rhythm.
