The Periodic Table of Scales
Only for Mac
Free · In‑App Purchases
Mac
Explore all 2,036 scales, find sounds by character, see each scale’s Character Spectrum, and hear real music transform as you move through the scale universe.
Find a scale by feeling—then hear what it does to real music.
Fantastic Scales maps all 2,036 scales of three or more notes into a universe you can see, hear, and explore. Of 2,048 tonic-rooted pitch collections, the 12 collections with fewer than three notes are intentionally omitted.
Search for something bright, dark, peaceful, mysterious, tense, epic, and more. Browse by family and structure. Open any Scale Portrait to see what makes it distinctive. See each scale’s Character Spectrum. Then hear the scale transform an included song—or bring in a MIDI idea of your own.
FIND THE SOUND BEFORE YOU KNOW ITS NAME
Search by Character to discover scales that feel bright, dark, peaceful, mysterious, epic, and more.
Or explore the underlying Sound Properties:
• Brightness
• Tension
• Activity
• Roughness
• Major Affinity
• Minor Affinity
Fantastic Scales ranks matching scales so you can move from a feeling to sounds you might never have found by name alone.
SEE EACH SCALE’S CHARACTER SPECTRUM
Every scale has a color spectrum showing how strongly it expresses eight Characters: Mysterious, Sad, Peaceful, Floating, Joyful, Epic, Restless, and Dramatic.
Like an emission spectrum, each Character keeps a fixed position while its intensity changes. The result is a second visual fingerprint for comparing scales.
THE PERIODIC TABLE OF SCALES
The scale universe is organized into families of related modes.
Explore three levels:
• Core — familiar and essential scale families
• Expanded — a broader world of musically significant scales
• Complete — all 2,036 scales
Browse one source scale from each family or reveal every distinct mode. Organization by mode count makes symmetry visible.
EVERY SCALE HAS A PORTRAIT
Each Scale Portrait combines structural properties into one visual identity: note count, distinct modes and transpositions, pitch structure, scale path, symmetry, fifths structure, source-family relationships, bi-triadic components, and interval fingerprint.
Open Reading This Scale Portrait to learn what each element means.
EXPLORE BY STRUCTURE
Full Access adds advanced filters and sorting by note count, mode count, symmetry, fifths structure, complete fifth arcs, and bi-triadic hexatonics.
HEAR WHAT THE SCALE CHANGES
Choose a scale and hear it transform an included Play-Along song.
Move between scales while the same musical idea continues playing and hear its character change—brighter, darker, calmer, stranger, more tense, or unexpected.
