In orchestral terminology, which term denotes a composition for one or more principal instruments, with orchestral accompaniment?

• A. A solo piece with no accompaniment
• B. A choral arrangement
• C. A drum solo
• D. A composition for one or more principal instruments, with orchestral accompaniment

Answer: (D)

The concept being tested is the term for a work that highlights one or more principal instruments with orchestral accompaniment: a concerto. A concerto is designed to showcase a soloist (or a small group of principal instruments) against the orchestra, which provides the accompaniment and engages in dialogue with the featured instrument. This matches the description of a composition for one or more principal instruments with orchestral backing. The other options don’t fit because they describe pieces without the orchestral spotlight on a principal instrument: a solo piece with no accompaniment has no orchestra; a choral arrangement centers on voices; a drum solo typically lacks orchestral partnership.
