Júrame in E

Júrame in E

María Grever, primera compositora latinoamericana en triunfar en Hollywood, escribió 'Júrame' en 1927. Plácido Domingo, Eydie Gormé y Pedro Infante la grabaron para generaciones distintas. El movimiento F-Fm en el puente — el mismo recurso modal de Somos Novios — es una de las firmas de la canción romántica mexicana: ese instante de oscuridad que hace brillar más el amor.

Júrame 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 C# (descending minor third), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to G# (descending minor third), G# to C# (ascending perfect fourth), C# to A (descending major third), A to A (ascending unison), A to E (descending perfect fourth). 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 E to E by unison.

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.
