This guide proves that all music can be transposed to any keys and you will see that the musical notes (intervals) remain equally spaced. (Hint: Double tap - return to original position)

- Change background
Try a different background whenever you want. Feel fresh when you study.
7 selected textures and 17 plain colors (random) x 16 different colored circles = 384 combinations!
