Infografía retro de teoría musical: circulo de cuartas guitarra

Music theory infographic titled "I–IV–V Chord Progression". Archetype: CIRCLE OF FIFTHS. Editorial music education poster in retro 1970s vinyl style, minimal monochrome palette, clean high-contrast black, cream, and gray inks, subtle paper grain, vintage geometric layout. Precisely render a 12-position circle of fifths ring with major keys on the outer ring and relative minor keys on the inner ring, evenly spaced and musically accurate. Visually emphasize the I–IV–V relationship with bold connecting lines and highlighted wedges showing how tonic, subdominant, and dominant are derived in any key. Include a clear central diagram explaining the harmonic function flow I → IV → V → I with simple roman numeral markers, interval arrows, and concise educational callouts in English. Add a small side panel with example I–IV–V progressions in common keys using canonical chord symbols only, such as C–F–G, G–C–D, D–G–A, A–D–E, E–A–B. Since the requested archetype is rhythm / time signature chart but the allowed archetype set is limited, integrate a compact auxiliary rhythm panel using neutral notation symbols only: simple bar groupings, 4/4 pulse grid, beat accents 1 2 3 4, and strumming-flow arrows without copyrighted melodies or lyrics. General theory focus, no instrument-specific fingering diagrams. Musically accurate spacing, hierarchy, and interval logic. Surrounding captions and headings in English, while note names and chord symbols remain in canonical international form. No copyrighted song lyrics or sheet music. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Musically accurate notation, finger positions and intervals. Note names and Italian musical terms stay in canonical international form. No copyrighted song lyrics or sheet music.
