Which instrument is featured as solo in Bach's Six Cello Suites?

• A. Violin
• B. Cello
• C. Flute
• D. Harp

Answer: (B)

The key idea here is that these works are written for a single instrument to perform all the music by itself. The Six Cello Suites are a famous cycle specifically titled for unaccompanied violoncello, BWV 1007–1012, so the instrument that carries the solo lines throughout the pieces is the cello. The writing exploits the cello’s range and legato capabilities, letting one player express the whole polyphonic texture of the suites without any accompaniment.

The other instruments listed don’t fit this collection because Bach’s suites in this set are not written for violin, flute, or harp; those instruments have their own separate repertoire and contexts. So the best answer is the cello, since the title and the music itself point to a solo cello performance.
