Perfidia in G

Perfidia in G

Perfidia in G — Alberto Domínguez's timeless bolero. The Bebop Major and Mixolydian scales work beautifully over these romantic changes. Chords: GMaj7 – Am7 – D7 – B7 – Em – G7 – CMaj7 – Cm6.

Perfidia in 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 A (ascending whole step), A to D (ascending perfect fourth), D to B (descending minor third), B to E (ascending perfect fourth), E to G (ascending minor third), G to C (ascending perfect fourth), C to C (ascending unison). 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 C to G by perfect fourth.

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.
