Stand by Me Chord Chart: 2–5–1 Guitar Infographic

Music theory infographic titled "2–5–1 Chord Progression for Guitar". GUITAR CHORD CHART archetype. Editorial music education poster, clean music education style, vibrant primary palette. Show a precise guitar-focused layout with three large vertical fretboard chord diagrams side by side illustrating a musically accurate ii–V–I progression in C major: Dm7, G7, Cmaj7. Each chord diagram must have 6 strings, at least 5 frets visible, clear nut or fret markers, exact finger position dots, open-string markers where needed, muted-string markers where needed, left-hand finger numbers, and note-name markers for chord tones. Include chord symbols above each diagram: Dm7 → G7 → Cmaj7. Add small interval annotations around each diagram identifying root, 3rd, 5th, and 7th for each voicing. Include a subtle horizontal arrow showing progression flow from ii to V to I. Add a small mini-diagram or caption panel explaining that ii–V–I is a common functional harmony cadence in jazz and pop, with clean educational callouts in English. Include a compact guitar neck reference showing string names E A D G B E. Visually emphasize smooth voice leading between the three chords.
