Nuestro Juramento in B

Nuestro Juramento in B

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 B

B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

The bass line moves through B to F# (descending perfect fourth), F# to E (descending whole step), E to D (descending whole step), D to A (descending perfect fourth), A to G (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from G to B by major third.

Scales for Improvisation

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