Steely Dan Chord Charts Minor Scales Theory Infographic

Music theory infographic titled "Natural, Harmonic, and Melodic Minor Scales". SCALE MODES archetype adapted as a general theory educational poster focused on minor scale comparison and common chord progressions. Retro 1970s vinyl design, minimal monochrome palette, clean editorial layout, subtle record-groove textures, bold geometric typography, high-contrast black, ivory, and soft gray. Central diagram shows three precisely notated minor scales side by side in staff notation with treble clef and keyboard interval references: Natural Minor, Harmonic Minor, Melodic Minor Ascending and Descending. Include accurate interval formulas and step patterns, clearly showing raised 7th in harmonic minor and raised 6th and 7th ascending in melodic minor, with descending melodic minor reverting to natural minor. Add a secondary panel with scale-degree harmonization and common chord progressions in minor keys, using musically accurate Roman numerals and chord symbols, for example i, iv, v, V, VI, VII, ii diminished, and progressions such as i–VII–VI–VII, i–iv–V–i, i–VI–III–VII, i–ii°–V–i. Show compact keyboard interval diagrams and simple note-to-degree mapping visuals for general theory, no instrument-specific fingering charts. Include precise note names in canonical form such as A, B, C, D, E, F, G and chord symbols such as Am, E7, Dm, G, Bdim where relevant.
