Tempo determines how fast music is played. Music typically follows a certain beat or meter, which drives the rhythm of the notes. The speed of this beat is measured in beats per minute. A higher number of beats per minute corresponds to a faster tempo, or playback speed.

You can use the classic music studio to change the tempo for a composition you created in the remixed music studio.
