Nuestro Juramento in E

Nuestro Juramento in E

Benicio Palacios Salas compuso 'Nuestro Juramento' en Ecuador en 1953. Julio Jaramillo la popularizó y se convirtió en el bolero más importante de Ecuador y uno de los más queridos del continente. 'Juro que jamás volveré a besar unos labios como los tuyos' — la letra es el arquetipo del juramento imposible. El Cm-G7 fluye con la gravedad de un bolero ecuatorial; el puente en Eb mayor es el momento en que el juramento aún parece posible antes de que el Cm lo deshaga.

Nuestro Juramento 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 C (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from C to E by major third.

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.
