Tú Mi Delirio in E

Tú Mi Delirio in E

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 E

E major is arguably guitar's most powerful key. The open low E and high E strings ring sympathetically as the root, while the open B provides the fifth. This triple reinforcement gives E-based riffs and chords unmatched depth and volume. E is a beginner-level key on guitar because both the low E and high E strings ring as the root, and the open B is the fifth — three open strings reinforce the tonic chord. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through E to E (ascending unison), E to F# (ascending whole step), F# to B (ascending perfect fourth), B to C# (ascending whole step), C# to A (descending major third), A to A (ascending unison), A to G# (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 G# to E by major third.

Scales for Improvisation

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