El Reloj in B

El Reloj in B — Roberto Cantoral's timeless bolero. The Bebop Major and Major Pentatonic scales work beautifully over these romantic changes. Chords: B – F#7 – C#m7 – Bmaj7 – E – Em – G#m7.

El Reloj 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 C# (descending perfect fourth), C# to B (descending whole step), B to E (ascending perfect fourth), E to E (ascending unison), E to G# (ascending major third). 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 G# to B by minor 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.
