HarmonyForge

Turn a pattern into music, and learn how harmony works. Arrange colors and shapes on a grid where the pattern IS the song, stack chords and intervals on a piano, and practice the ideas across 16 kits. Take it at your own pace — everything works with the sound off.

Make and explore

Your studio and your lab — arrange a pattern that plays as music, and build chords and intervals by ear or by eye. Both work fully with the sound off.

Pattern Grid Studio Arrange colors and shapes on a grid — top to bottom is high to low, left to right is time. Press play and watch the pattern become music. Pick a calm room, and save your patterns to this device. Chord & Interval Lab Build intervals and triads on a silent piano — stack a root, third and fifth, or find the note a Perfect 5th up. See which sounds settle and which want to move. A hint is always there after a first try. Circle of Fifths Spin around the wheel of keys — each step clockwise is up a Perfect 5th and adds a sharp. Find a key's dominant (where it would Shift to), its relative minor, and the key for any number of sharps or flats.

Learn about music

16 question rounds — rhythm, melody, notation, instruments, harmony, history and more. A hint is always there when you want one. Take them in any order.
