Musical scale builder
Build a scale with correctly ordered note-letter spellings.
A clear answer. Here’s how.
Uses fixed semitone patterns for the selected scale and letter steps for each scale degree. Retains key-appropriate sharps, flats and double accidentals rather than simply renaming every pitch. Includes the octave above the root. Melodic minor here is the ascending form; outputs must stay in MIDI range 0–127.
