Your harmonic journey
Place notes on the hex grid by clicking empty cells.

Hold (H) saves a note for later. Discard skips one (costs points).
Intervals are the distance between two notes, measured in semitones.
Adjacent notes with harmonious intervals form chords.
Chords are groups of adjacent notes that sound harmonious together.
