How do phrases in Sweet Georgia Brown modulate?

• A. Each phrase modulates to a key that is a perfect fifth lower than the preceding phrase
• B. They remain in the same key throughout
• C. Each phrase modulates up a perfect fourth
• D. They modulate randomly by semitones

Answer: (A)

Sweet Georgia Brown uses a circle-of-fifths approach to modulation: each new phrase lands in a key whose tonic is a perfect fifth lower than the previous one. That effect, thinking in pitch, is the same as moving down a fifth or, equivalently, up a fourth, creating a continuous, cohesive descent through related keys. If you hear a starting phrase in a given key, the next phrase tends to sit in the key a fifth lower, then the one after that another fifth lower, and so on. This pattern matters because it gives the tune a forward-driving harmonic motion while staying within closely related keys, which helps improvisers navigate the changes and keeps the texture bright and connected. Staying in one key would feel static; moving up a fourth would produce a different directional pull and color; random semitone shifts would break the sense of coherence that the circle of fifths progression provides.
