Tú Mi Delirio in G

Tú Mi Delirio in G — César Portillo de la Luz's timeless bolero. The Bebop Major and Major Pentatonic scales work beautifully over these romantic changes. Chords: G – Gmaj7 – Am7 – D7 – Em7 – C – Cm – B7.

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.
