The Tuna project consists of a platform game, where each level features a new song that introduces new skills and musical connections. The game utilizes an adapted version of the Tonnetz diagram to facilitate music creation and learning. The main feature of this matrix is that it allows for easy visualization of musical theory concepts such as scales, chords, etc., through geometries like triangles and diamonds. Tuna aims to be a fun game for learners and creators of all ages.
