O Que Será 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 G (ascending unison), G to G (ascending unison), G to G (ascending unison), G to D (descending perfect fourth), D to D (ascending unison), D to D (ascending unison), D to E (ascending whole step), E to C (descending major third), C to C (ascending unison), C to C (ascending unison), C to C (ascending unison), C to D# (ascending minor third), D# to D# (ascending unison), D# to A (ascending tritone), A to D (ascending perfect fourth), D to D# (ascending half step), D# to D# (ascending unison), D# to A# (descending perfect fourth), A# to F# (descending major third), F# to D (descending major third), D to C (descending whole step), C to G (descending perfect fourth), G to A (ascending whole step), A to F (descending major third), F to F (ascending unison), F to F (ascending unison), F to F (ascending unison), F to G# (ascending minor third), G# to G# (ascending unison), G# to D (ascending tritone), D to G (ascending perfect fourth), G to G# (ascending half step), G# to G# (ascending unison), G# to D# (descending perfect fourth), D# to B (descending major third), B to G (descending major third), G to A (ascending whole step), A to D (ascending perfect fourth), D to A (descending perfect fourth), A to A (ascending unison), A to A (ascending unison), A to B (ascending whole step), B to A# (descending half step), A# to A# (ascending unison), A# to E (ascending tritone), E to A (ascending perfect fourth), A to A (ascending unison). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. 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.
