A band is a group of musicians who come together to create and perform music. They can vary in size, from small duos to large orchestras, and often play different genres like rock, jazz, or pop. Each member usually plays a specific instrument, such as the guitar, drums, or keyboard, and they work together to create a unique sound. Bands often perform live at concerts or festivals, allowing fans to enjoy their music in person. Some famous bands, like The Beatles or Queen, have made a significant impact on music history and continue to inspire new artists today.
