Final Thoughts

  • Index finger (1): 2nd fret, 3rd string (G string)
  • Middle finger (2): 2nd fret, 4th string (D string)
  • Ring finger (4): 3rd fret, 2nd string (B string)
  • Thumb (or pinky) – added octave: On the 5th fret, 1st string (high E string) — optional for fuller tone; not always necessary

🔹 Optional thumb/pinky extension: Placing your pinky on the 5th fret, 1st string adds a bright sharpness and strengthens the chord’s presence without being required in basic shapes.

Strumming Tip: Start strumming from the high E string downward, emphasizing the full rich texture. Begin slowly and smooth out transitions, especially when integrating the 9th and 13th subtleties.
