Scale finder

Choose a root and scale to see its notes and the intervals around one octave. Piano colours mark scale notes, with the tonic darker. The fretboard shows all matching positions in standard E A D G B E tuning, not a suggested fingering. Scroll a narrow fretboard horizontally.

Reverse search finds every supported scale containing the entered pitch classes. Repeated notes and enharmonic names count once. Optionally specify a tonic; a few notes cannot establish a unique key. Results rank by fewest additional notes. All matching scales are available in the optional table.

There are 20 families: diatonic modes, natural/harmonic/ascending melodic minor, pentatonics, minor blues, whole-tone, chromatic, and six further defined scales. Melodic minor here uses the ascending form. Traditional names can refer to different variants; these are 12-tone equal-tempered collections. The step sequence states the exact definition.

International letters use B for German H and Bb for German B. Notes accept #/♯, b/♭ and double accidentals. Scale spelling follows diatonic degrees where applicable; symmetric chromatic/whole-tone collections use enharmonic pitch names. Minor blues uses1 b3 4 b5 5 b7.

Identical chromatic and whole-tone collections are grouped when no tonic is specified; the displayed root is a representative. Specify a tonic to inspect another starting note.

Selections draw immediately. Matching scales update while you type or choose a tonic. Select a scale name in the complete scrollable table to show its instruments; extra notes occupy their own column. Only raw inputs are remembered, including unfinished or invalid note lists. Results and the expanded search view are temporary.
