ii–V–I Music Theory Infographic | guitarchord chart

Music theory infographic titled "ii–V–I Chord Progression". Archetype: SCALE MODES infographic (Ionian → Locrian), adapted for general theory and centered on a musically accurate visual explanation of the ii–V–I progression. Retro 1970s vinyl editorial poster style, minimal monochrome palette, clean geometric layout, subtle print texture, high contrast, elegant vintage modernist typography. Main diagram: a horizontal sequence showing the harmonic function of ii → V → I with precise interval construction and mode relationships, using canonical chord symbols and note names only. Include seven aligned mode panels from Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian to Locrian, with interval formulas and scale-degree markers rendered accurately; visually emphasize how Dorian relates to ii, Mixolydian to V, and Ionian to I in a major key context. Add a clear functional flow from supertonic to dominant to tonic, with arrows, stacked tertian chord construction, root–3rd–5th–7th chord tones, and optional example in C major using Dm7 → G7 → Cmaj7. Include precise interval labels, Roman numerals, staff-inspired theory accents, and abstract circular vinyl-record motifs integrated into the composition. No instrument-specific fingering unless represented as abstract theory markers; if any position markers appear, ensure they are musically accurate. No copyrighted song lyrics or sheet music excerpts. Target search intent visually suggests a guitarchord chart aesthetic without making it a fretboard chart.
