All 351 families of notes in twelve-tone music, mapped and playable. The complete companion to The Color Tree, now on iOS.
Every sound available in twelve-tone music - all 2,048 of them, organized into 351 "colors" - playable and searchable wherever you go.
This Encyclopedia is a complete map of musical space. Each of the 351 unique families of notes gets an entry: hear it, visualize it, learn its name and how it relates to everything around it. Familiar scales and chords sit alongside thousands more - most musicians have never encountered.
You may already know The Color Tree, the special-case sounds whose notes are all adjacent along the circle of fifths, organized from simple to complex and dark to bright. The Encyclopedia contains those 67 sounds - and every other sound there is.
Key Features:
• Fully offline - the whole map, no connection required
• Listen to any color - customizable playback for every set of notes
• Scale visualizer - see the notes laid out on your instrument of choice
• Filter and search - narrow by scale degree, interval range, and more
• Curated and custom lists - browse collections or build your own favorites
• Reactive UI - a dynamic sky background that responds to your selections
• Randomize - surprise yourself with sounds you've never heard!
For composers, improvisers, theorists, sound designers, and anyone who has ever wondered what else is out there.
• Loop is now a toggle, and looping playback is gapless.
• The circle wheel and its controls now lay out correctly on smaller screens.
• Rotating the wheel feels immediate — the selection now lands together with the connecting lines instead of trailing behind them.
• Upside-down portrait is now supported.
• A new tip link under Feedback in Settings.
• Refreshed color and mode names throughout.
