Bilongo in B
Bilongo in B
Bilongo in B: Guillermo Rodríguez Fiffé's minor guaracha. Dorian and Harmonic Minor scales give this groove its characteristic dark edge. Chords: Bmb5 – C9 – F#7 – Em6 – F#7(#9) – A9 – D9 – G9 – G7 – F#9 – Bm6 – DMaj9 – C6b5 – B9 – Em7 – D#9 – DMaj7 – Am7 – D13 – G#7alt.
Bilongo 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 C (ascending half step), C to F# (ascending tritone), F# to E (descending whole step), E to F# (ascending whole step), F# to A (ascending minor third), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to G (ascending unison), G to F# (descending half step), F# to B (ascending perfect fourth), B to D (ascending minor third), D to C (descending whole step), C to B (descending half step), B to E (ascending perfect fourth), E to D# (descending half step), D# to D (descending half step), D to A (descending perfect fourth), A to D (ascending perfect fourth), D to G# (ascending tritone). A half-step bass movement creates a strong leading-tone pull that demands resolution. 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.
