Which Scarlatti sonata is in G Major and written in binary form?

• A. Sonata in D Major
• B. Sonata in GM
• C. Sonata in F Minor
• D. Sonata in C Major

Answer: (B)

Recognizing tonal center and binary form. Scarlatti’s keyboard sonatas are typically built in binary form, with two distinct halves that move away from the home key in the first section and then head toward a cadence that often returns to or reinforces the home key in the second. The prompt requires a sonata that is in G major, so the key aspect must be G major. Among the options, only the one in G major satisfies this key requirement, while the others are in D major, F minor, or C major. Since both conditions—G major and binary form—need to be met, the G major binary piece is the correct choice.
