A composer wants to build urgency as the music approaches a climax. Which harmonic rhythm strategy would best achieve this?
ASustain a single chord for 8 bars before the climax
BChange chords every four beats throughout
CGradually increase chord-change frequency, reaching chord changes every beat near the climax
DEliminate chord changes entirely at the climax to create stillness
Accelerating harmonic rhythm mimics the feeling of increasing activity and forward momentum. As chords change more frequently, the listener senses energy building — a common technique in Baroque sequences and Romantic developmental passages. Holding a single chord creates stability or stasis, the opposite of urgency.
Question 2 True / False
A piece with a very slow tempo should also have a slow harmonic rhythm.
TTrue
FFalse
Answer: False
Harmonic rhythm (rate of chord change) and tempo (rate of beat) are completely independent dimensions. A slow-tempo piece can have chords changing every single beat, creating a sense of thick, active harmony. Conversely, a fast piece might sit on one chord for many bars, producing a feeling of openness or suspension. Composers manipulate both independently to shape musical character.
Question 3 Short Answer
How does harmonic rhythm differ from melodic rhythm, and why does the distinction matter for composers?
Think about your answer, then reveal below.
Model answer: Harmonic rhythm is the rate at which chords change; melodic rhythm is the pattern of note durations in a melody. They operate independently — a melody can move in rapid sixteenth notes over a static harmony, or long held notes over fast-changing chords.
Understanding these as separate dimensions gives composers precise control over texture. A fast melody over slow harmony creates a soloist-over-drone effect; slow melody over fast harmony creates density and complexity. Recognizing that these are independent variables is essential for analyzing why a passage sounds the way it does and for making intentional compositional choices.
