A music group, often referred to as a band, is a collection of musicians who come together to create and perform music. These groups can vary in size, ranging from small duos to large ensembles, and they often specialize in specific genres such as rock, jazz, or pop. Members typically play different instruments or sing, contributing to the overall sound and style of the group. Music groups can perform live at concerts, festivals, and events, or they may record their music in studios for distribution. Many famous music groups, like The Beatles or Queen, have made significant impacts on the music industry and culture, influencing countless artists and fans around the world.
