How to Read a Guitar Chord Diagram

  1. The vertical lines represent the six guitar strings. In a standard diagram, the low E string is on the left and the high E string is on the right.
  2. The horizontal lines represent frets. A thick line at the top is the nut; a number beside the diagram indicates a shape that starts higher on the neck.
  3. A filled marker tells you where to press. Finger numbers usually mean index 1, middle 2, ring 3, and little finger 4.
  4. An open marker means play that string without fretting it. A muted marker means do not sound that string.
  5. Strum slowly once, then check every string separately. Adjust any finger that causes a neighboring string to buzz or stop ringing.

How to Choose the Best Voicing

The correct chord name does not imply only one shape. Choose a voicing by listening to its top note, checking how far your hand must move from the previous chord, and deciding whether open strings fit the arrangement.

Open chords are often comfortable for beginners and resonate clearly. Movable shapes let you reuse a fingering in other keys and can keep a progression in one area of the neck. For songwriting, compare two or three voicings and listen to the motion of the highest note rather than choosing by shape alone.
