This is Beethoven's Moonlight Sonata (3rd Movement). It shows which piano keys are being pressed by showing a light over the keys. The brightness is based on how hard the note is being played (note velocity). This app was made with 3dsMax for video and FL Studio for the music/audio. We used a synthesizer instead of a piano for a high tech feel. Enjoy! The entire song is 6 minutes and 26 seconds.
