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 - choose your answer by selecting 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. Your musical knowledge will increase with repeated playing of the game. You can choose between piano and organ voices for playing the chords.
