Musical groups, often called bands or ensembles, are collections of musicians who come together to create and perform music. These groups can vary in size, ranging from small duos to large orchestras, and can play various genres, including rock, jazz, classical, and pop. Each member typically plays a specific instrument or sings, contributing to the overall sound of the group. Many musical groups collaborate to write original songs or perform covers of existing music. They often perform live at concerts, festivals, and events, and may also record albums for distribution. Famous examples of musical groups include The Beatles, Queen, and The Rolling Stones.
