This seemed a natural extension of a piano app. If we’re catching keyboard input and playing music, there’s no reason not to integrate them into a “reverse guitar hero” game. The game would have two modes, seeing notes and playing them, a la guitar hero, and the reverse, hearing notes and playing them (feedback in form of musical notation and applause). One concern is that the game is not very stunningly musical on easy levels.

Design 1:
It allows users to ear train. After hitting start, machine starts playing notes according to difficulty level, and the user guesses the notes by playing them on keyboard. User can also share expertise (which difficulty level he is doing) to his friends. (Hitting “share expertise” button will give him a link, which states his expertise, to email to other people.\
Design 2:
It allows users to “free-play” keyboard as well as record what they play. The user can extract the recorded music and get it as a text of notes, to refer at a later time or email to friends.

In this design (although not drawn out properly), the user is supposed to have a longer form to fill out in order to enter his previous experience. When the user logs in, he already sees a bunch of items on the list marked as “Done”. These will exactly be the things that the user probably knows as inferred from the information provided while creating the account. The user is, however, given the option to go through these courses by marking them as “todo”.
