Two drums are custom outfitted with piezo sensors to detect a player’s input. The game is controlled using custom software written in Processing. The software is able to rate the musical accuracy of a user’s input, and adjusts a “reward spectacle” accordingly. A “combo counter” is responsible for displaying the number of consecutively scored notes.

One element of the game left unfinished is a “call and response” or “volley” mechanic. Certain phrases, if completed in their entirety, are “volleyed” to one’s opponent, who sits across the playing field. The desired effect is to create a sense of “echo” or musical interaction, deviating from the prevailing linear structure of sight-reading rhythm games.
