Scale Finder — Find Musical Scales from Notes Online
Select a set of notes to discover which musical scales contain them. Covers major, minor, modal, and exotic scales across all twelve keys. 100% client-side — nothing leaves your browser.
How to Use the Scale Finder
- Select notes — click the note buttons that appear in your melody or chord.
- Review matches — scales are ranked by how many of your notes they contain, best first.
- Spot matches — the green notes show which of your selections belong to each scale.
- Refine — add more notes to narrow the results to fewer, more specific scales.
Why Use This Scale Finder
When transcribing or writing music it's invaluable to know which scale a melody belongs to. This tool compares your selected notes against a library of common and exotic scales in all 12 keys, then ranks every scale by how well it fits. It's an essential companion for improvisation, songwriting, and music theory study.
Pair it with the Chord Identifier to analyse harmony, or with the Melody Generator to write new lines within a chosen scale.
Frequently Asked Questions
More than 20 scale types across all 12 keys — major, natural/harmonic/melodic minor, pentatonic, blues, Dorian, Phrygian, Lydian, Mixolydian, Locrian, whole-tone, chromatic, diminished, and more. Each is available in every transposition.
Scales are sorted by the number of your selected notes they contain (descending), then by name. A scale containing all of your notes is a perfect match; partial matches may still be useful for a melody built mostly in one scale.
The Chord Identifier finds which chord a group of notes forms. The Scale Finder finds which scales contain your notes — useful when working with melodies, solos, or full song tonalities rather than single chords.
