Question 1: Which texture describes a single melodic line accompanied by chordal harmonies that support but do not imitate the melody?
- Polyphony
- Monophony
- Homophony (Correct answer)

Question 3: What formal term describes the technique of restating an entire section of music at a higher or lower pitch level?
- Sequence
- Transposition (Correct answer)

Correct answer: Transposition
Transposition moves all pitches of a passage by a consistent interval, preserving the melodic and harmonic relationships at a new pitch level.

Melodic variation (or ornamented variation) preserves the theme's harmonic framework while elaborating or decorating the original melody.
