The player controls Tempo, a Harmoknight in training. Players must hit and jump as Tempo travels through automatic scrolling levels. The goal of each level is to collect as many notes as possible by either hitting enemies or Percussiplants. Players can charge up Tempo's staff to gain a extra note if the next hit is successful. Occasionally, the player will have to control Lyra, who can shoot enemies from a distance with her harp, or Tyko and Cymbi, who will pound all enemies in their way. A few levels will take place on a mine cart that will constantly change the tempo of the music. Boss levels have the player repeating a sequence of actions to the beat.
