The app consists of three sections:

In "Play Game" mode, you can test and improve your skill in determining musical pitch. Press the play button and a tone will sound. Then press and hold down the corresponding note on the violin fingerboard. Compare the two sounds! When the note is released, a message displays the result. The game has 12 levels, and you must complete each level to progress to the next.

In "Practice" mode, you can learn where the notes are placed on the violin fingerboard. Get to know the sound of notes by pressing individual notes on the fingerboard. Play melodies by controlling the length of the sound by releasing the note. When released, the note stops sounding. Play chords using multiple fingers. If you don't release the note, it will stop sounding after some time.

In "Make Game" mode, you can create and play your own custom games in addition to the standard game.
