Nuestro Juramento in A

Nuestro Juramento in A

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 A

A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

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

Scales for Improvisation

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