A "click track" is a metronomic audio guide used in music production to help musicians stay in time while recording or performing. It typically consists of a series of audible clicks or beats that align with the tempo of the song. This tool is especially useful in studio settings where multiple instruments are recorded separately. Click tracks are commonly used in various genres of music, including pop, rock, and classical. They can be played through headphones, allowing musicians to hear the clicks without them being recorded in the final mix. This ensures a tight and cohesive performance, making it easier to edit and produce the final track.
