Music groups, often called bands or ensembles, are collections of musicians who come together to create and perform music. They can vary in size from small duos to large orchestras, and they often specialize in specific genres like rock, jazz, or classical. Each member typically plays a different instrument or contributes vocals, working collaboratively to produce a cohesive sound. These groups can perform live at concerts, festivals, or events, and they may also record music in studios. Some well-known music groups include The Beatles, Queen, and The Rolling Stones. Music groups play a significant role in the music industry, influencing culture and trends.
