The G chord is one of the first chords many musicians learn, regardless of the instrument they play. It’s a foundational chord that opens the door to understanding music theory, chord progressions, and playing a ton of popular songs.
This guide offers a complete overview of the G chord, including how it’s formed, different ways to play it, and how it’s used on guitar and piano. We’ll break down the notes that make up the G chord, explore inversions, and show you how it functions within the key of G major.
The G Major Chord: Notes and Construction
The G major chord is a triad, which means it’s built from three notes: G, B, and D.
Understanding how the chord is constructed is key to understanding basic music theory. The G major chord includes a root note (G), a major third (B), and a perfect fifth (D).
On guitar, to play a G major chord, you have to press down on specific strings to create those notes. Most fingerings involve using your index, middle, and ring fingers on different frets on the E, A, and high E strings.
On piano, you play a G major chord by pressing the G, B, and D keys at the same time.

G Chord Inversions on Piano
When you play a G chord on the piano, you don’t have to keep the G as the lowest note. Changing the order of the notes creates what’s known as an inversion, and these inversions can give you different sounds and ways to harmonize.
G/B (First Inversion)
In the first inversion of a G chord, the B is the lowest note you play. So, the notes are arranged B-D-G.
There are several ways to finger this chord. But a common fingering for the right hand is 1-3-5 (thumb, middle, pinky).
G/D (Second Inversion)
In the second inversion, the D is the bass note, so the notes are arranged D-G-B.
A possible fingering here is 1-2-5 (thumb, index, pinky).
Common Chord Progressions in G Major
Understanding chord progressions helps you write songs and improvise. One of the most common chord progressions is I-IV-V, which is G-C-D in the key of G major. Another popular progression is I-V-vi-IV, or G-D-Em-C. These are great places to start when you’re writing your own music.

The G chord is more than just a basic chord; it’s a gateway to more complex music. When you understand the G chord’s construction, different versions, and how it’s used in music, you unlock a world of possibilities.
Whether you play guitar, piano, or write songs, mastering the G chord is an essential step in your musical journey.
