The G Major Open Chord for Guitar

The Formula of the Chord

The G major chord is one of the most fundamental chords in guitar playing, known for its bright and resonant sound. The formula for a major chord consists of three intervals: the root (R), the major third (3), and the perfect fifth (5). In the case of the G major chord, the specific notes involved are:

• Root (R): G
• Major Third (3): B
• Perfect Fifth (5): D

In the open G major chord that uses three fingers, the voicing we play includes these notes distributed across the strings as follows:

• 6th string (E): G (R)
• 5th string (A): B (3)
• 4th string (D): Open D (5)
• 3rd string (G): Open G (R)
• 2nd string (B): Open B (3)
• 1st string (E): G (R) 

How to Play the Chord

To play the G major open chord using three fingers, follow these step-by-step instructions:

1. Index Finger: Place your index finger on the 2nd fret of the 5th string (A string). This will produce the note B (3).
2. Middle Finger: Place your middle finger on the 3rd fret of the 6th string (E string). This will produce the note G (R).
3. Ring Finger: Place your ring finger on the 3rd fret of the 1st string (high E string). This will produce the note G (R).

Make sure that your fingers are pressing down firmly just behind the frets to get a clear sound. Let the remaining strings (4th, 3rd, and 2nd) ring open, as they are part of the chord:

• 4th string (D): Open, producing the note D (5)
• 3rd string (G): Open, producing the note G (R)
• 2nd string (B): Open, producing the note B (3)

Strum all six strings together to play the G major open chord.
