Open Guitar Chord Chart Infographic in Retro Vinyl Style

Music theory infographic titled "Open Guitar Chord Chart". GUITAR CHORD CHART archetype, rendered as a precise editorial music education poster in retro 1970s vinyl style with a minimal monochrome palette. Central layout: a clean set of accurate open-position guitar chord fretboard diagrams, each with 6 strings and clear fret spacing, nut line emphasized, finger positions marked precisely, open strings indicated, muted strings indicated, and chord symbols in canonical form such as C, G, D, A, E, Am, Em, Dm. Include small supporting rhythm and time-signature visual references as secondary elements only, using simple measure icons and beat-grouping graphics, but keep the main focus on the open guitar chord chart. Show interval relationships and string-to-note mapping where appropriate with musically accurate notation. General theory presentation, no copyrighted song lyrics or real sheet music excerpts. Visual tone: vintage record-sleeve graphic design, bold geometric composition, subtle print texture, high contrast black, off-white, and muted gray, minimal ornament. Include only English captions and headings around the diagrams; note names, chord symbols, and Italian musical terms remain in canonical international form. Avoid any branding or product-reference text, and do not visually depict a pickup wiring chart. 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.
