A backing track is a musical accompaniment used by musicians, typically instrumental, to support or accompany their performance. It serves as a background for a soloist or ensemble, allowing them to play or sing over the pre-recorded music. Backing tracks can include various elements like rhythm sections (drums, bass, and percussion), harmonies, and additional instruments, providing a full sound to complement the live performance. Musicians often use backing tracks during live shows, karaoke, practice sessions, or in recording studios to enhance the overall sound and create a more dynamic and complete musical experience.
