Perfidia in G

Perfidia in G

Alberto Domínguez compuso 'Perfidia' en 1939 en Guatemala. Glenn Miller, Xavier Cugat y los Tres Diamantes la convirtieron en estándar internacional. Nat King Cole la grabó en español, y The Ventures la pusieron en los tops de instrumentales en 1960. La palabra 'perfidia' —traición— resume uno de los grandes temas del bolero latinoamericano: el amor traicionado con elegancia melancólica.

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 D (descending perfect fourth), D to C (descending whole step), C to A# (descending whole step), A# to F (descending perfect fourth), F to A (ascending major third). 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.
