Scale Finder

Pick a root note and a scale or mode, and see it laid out on the keyboard

Choose a root note and a scale or mode below to light up its notes on the keyboard, with a note-by-note breakdown underneath. The seven standard modes plus Harmonic and Melodic Minor show scale degrees as Roman numerals, correctly cased and marked for diminished (°) and augmented (⁺) chords built on that degree. Pentatonic and blues scales show plain scale-degree numbers instead, since Roman numeral analysis doesn't apply to non-diatonic note sets.
