Tú Mi Delirio in B
Tú Mi Delirio in B
César Portillo de la Luz escribió 'Tú Mi Delirio' en 1954, una de las obras más refinadas del filin cubano. 'Tú eres la razón de mi existir' con la elegancia armónica del jazz cubano. Ibrahim Ferrer la grabó con el Buena Vista Social Club y la llevó a los escenarios internacionales. La cadencia IV menor (Cm en G mayor) —tan característica del bolero sofisticado— añade una sombra romántica perfecta.
Tú Mi Delirio 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 B (ascending unison), B to C# (ascending whole step), C# to F# (ascending perfect fourth), F# to G# (ascending whole step), G# to E (descending major third), E to E (ascending unison), E to D# (descending half step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from D# 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.
