✅ How to Read a Chord Diagram
- Vertical lines = the 6 strings. Left is the low E (thickest), right is the high e (thinnest).
- Horizontal lines = frets. The nut is at the top for open chords; a fret number shows position for barre chords.
- Filled dots = place a finger there. The number inside = which finger (1=index, 2=middle, 3=ring, 4=pinky).
- X above a string = mute or don't play that string.
- O above a string = play it open (no fingers).
- A curved bar across strings = barre — press one finger flat across all those strings.
Frequently Asked Questions
How do I read a guitar chord diagram?
The diagram shows the fretboard from the front. Vertical lines are strings (low E on left), horizontal lines are frets. Filled dots show finger placements. X = mute, O = open string.
What do the numbers on chord diagrams mean?
Numbers inside dots indicate which finger to use: 1 = index, 2 = middle, 3 = ring, 4 = pinky. A curved bar across multiple strings means a barre — press one finger flat across all of them.
What is the difference between a major and minor chord?
Major chords use a major third (4 semitones above the root) giving a bright, happy sound. Minor chords use a minor third (3 semitones) giving a darker character. C major = C-E-G, C minor = C-E♭-G.
What is a barre chord?
A barre chord uses one finger pressed flat across all 6 strings at one fret, acting as a movable nut. This lets you play the same chord shape anywhere on the neck, changing the root note with each position.
Which chords should a beginner learn first?
Start with the open chords: E major, A major, D major, G major, C major, E minor, A minor, and D minor. These cover hundreds of songs and build the finger strength needed for barre chords later.
