Which term describes the rhythmic properties of the tonal system, including recurrence of tones and octave relationships?

• A. Beat
• B. Tonal rhythm
• C. Arpeggiation
• D. Scherzo

Answer: (B)

Tonal rhythm describes how rhythm is shaped by the way the tonal system organizes pitches and their octaves. It accounts for the recurrence of tones—motives and scale degrees that reappear in melodies or harmonies—and the relationships of those tones across octaves, which makes related pitches feel connected over time. This goes beyond a simple pulse, since the timing listeners perceive is influenced by how tonal centers and pitch classes reappear and relate across registers. The other options describe different ideas: the beat is the regular pulse, arpeggiation is breaking chords into a sequence of notes, and a scherzo is a musical form.
