In Bach's Brandenburg Concertos, which keyboard instrument is featured prominently in the fifth concerto?

• A. Harpsichord
• B. Piano
• C. Clavichord
• D. Organ

Answer: (A)

This concerto centers on a keyboard instrument and the writing makes that instrument the star. Bach gives the harpsichord a full solo role, culminating in a long, virtuosic cadenza that sits at the heart of the movement, with the violin and flute weaving around it as partner voices. The harpsichord’s bright, precise, plucked-tone is perfect for rapid runs and intricate figuration, which is exactly what the solo keyboard part demands here. In Bach’s time the piano hadn’t yet appeared, the clavichord wouldn’t carry over an ensemble in a big concerto, and the organ would bring a different, churchly color rather than the secular virtuosity this piece showcases. So the keyboard instrument highlighted in this concerto is the harpsichord.
