Perfidia in E

Perfidia in E

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 E

E major is arguably guitar's most powerful key. The open low E and high E strings ring sympathetically as the root, while the open B provides the fifth. This triple reinforcement gives E-based riffs and chords unmatched depth and volume. E is a beginner-level key on guitar because both the low E and high E strings ring as the root, and the open B is the fifth — three open strings reinforce the tonic chord. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through E to B (descending perfect fourth), B to A (descending whole step), A to G (descending whole step), G to D (descending perfect fourth), D to F# (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 F# to E by whole step.

Scales for Improvisation

E 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, E Mixolydian adds the flat seventh for an authentic blues-rock edge.
