A studio musician is a professional musician who records music in a studio setting, often for various projects like albums, commercials, or film scores. They are skilled in playing multiple instruments and can adapt to different musical styles, making them valuable for producers and artists looking to enhance their recordings. These musicians typically work on a freelance basis, collaborating with producers, singers, and other artists. They may also be involved in arranging music and providing creative input during recording sessions, contributing to the overall sound and quality of the final product.
