Tú Mi Delirio in G

Tú Mi Delirio in G

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 G

G major is the singer-songwriter's key. The open G, B, and D strings spell out the full G major triad with zero fretting. Add the open high E for a Gadd6 shimmer. Nearly every diatonic chord (Em, Am, C, D) has a comfortable open voicing. G is a beginner-level key on guitar because the open G, B, and D strings form a complete G major triad without fretting a single note, and the open low E adds a rich 6th color. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

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

Scales for Improvisation

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