Blue Moon in G

Key of G

G major is the singer-songwriter's key. The open G, B, and D strings spell out the full G major triad with zero fretting. Add the open high E for a Gadd6 shimmer. Nearly every diatonic chord (Em, Am, C, D) has a comfortable open voicing. G is a beginner-level key on guitar because the open G, B, and D strings form a complete G major triad without fretting a single note, and the open low E adds a rich 6th color. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through G to E (descending minor third), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to F (ascending minor third), F to E (descending half step), E to D# (descending half step), D# to G (ascending major third), G to G (ascending unison), G to C (ascending perfect fourth), C to B (descending half step), B to C# (ascending whole step), C# to C (descending half step), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to D (ascending major third), D to A (descending perfect fourth). A half-step bass movement creates a strong leading-tone pull that demands resolution. The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from A to G by whole step.

Scales for Improvisation

G major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, G Mixolydian adds the flat seventh for an authentic blues-rock edge.
