Updated for the latest version of Android.

Store description

Challenge your musical skill with Interval by determining which chord was played. For each puzzle, three chords are played with the musical notation displayed for the first two. The third chord will be one of four choices displayed - choose your answer by touching the right chord. The point value for each game will be added to your score for the correct answer, but half the points will be deducted for each wrong one. You can play the three chords as many times as you like, and you can move on to the next puzzle without answering and without penalty. Your musical knowledge will increase with repeated playing of the game. You can choose between piano and church organ for the game's instrument.
