Which composer is associated with 'light conservational chamber works and keyboard music' and also wrote operatic works?

• A. W. F. Bach
• B. Domenico Scarlatti
• C. J. C. Bach
• D. C. P. E. Bach

Answer: (C)

Think about a composer known for light, salon-friendly chamber and keyboard music who also wrote operas. Johann Christian Bach fits this blend: he helped popularize the galant, conversational style in late 18th-century chamber and keyboard works, designed for intimate performance settings, and he also produced operatic works. This combination—accessible instrumental music alongside vocal drama—marks him as the best fit for the description. By contrast, Domenico Scarlatti is celebrated mainly for virtuosic keyboard sonatas; the other Bach sons are associated with different emphases, not the same notable pairing of light chamber/keyboard music and operatic writing.
