Nuestro Juramento in C

Nuestro Juramento in C

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 C

With no sharps or flats, C major is the theoretical home base on guitar. The open G, B, and high E strings all belong to the C major chord, creating natural sustain. C is a beginner-level key on guitar because the open B and high E strings ring within the scale, and every basic chord uses familiar open shapes. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through C to G (descending perfect fourth), G to F (descending whole step), F 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 C by major third.

Scales for Improvisation

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