A small group of musicians that play rock or popular music.

• A. Jazz combo
• B. Rock band
• C. Big band
• D. Orchestra

Answer: (B)

In rock and popular music, a small group that plays together is typically called a rock band. This kind of ensemble is built around a core rhythm section—drums and bass—plus electric guitar(s) and a vocalist, with keyboards often added. The setup is designed for amplified sound, tight groove, and energetic, interactive playing where guitars and vocals carry melodies and hooks while the rhythm section drives the beat. The other ensemble types point to different traditions: a jazz combo is a smaller group focused on jazz nuance and improvisation; a big band is a larger jazz-focused ensemble with multiple brass and reed sections and a rhythm section; an orchestra is a large classical ensemble with strings, winds, brass, and percussion. So the described group aligns with the rock band, reflecting both its typical lineup and its popular-music focus.
