In this musical arcade game, you serve as the head of Project Unison. It is your mission to collect harmonic orbs from the note nebula. Your eyes will help at first, but as you enter the nebula you'll need to rely on your ability to recognize musical intervals with your ears. Brought to you by the award-winning educational video game studio, Filament Games.

Listen to the notes emitted by the orbs and identify the interval to catch them. When you miss ten orbs, the mission will end and you will return to base. Keep playing to train your ears and get a better high score.

An interval is the difference between two pitches, and interval ear training is a vital element of understanding music theory.

Whether you are a novice, or a seasoned musician, each time you beat your last high score, you will be genuinely improving your musicality and understanding of intervals.
