Tin Tin Deo in A#

Tin Tin Deo in A#

Gil Fuller and Chano Pozo's 1947 Afro-Cuban jazz classic — the chromatic descent Fm6–Ebm6–DbMaj7–C7 mirrors Yoruba rhythmic cycles, bridging bebop and santería. Dizzy Gillespie's big band version made it an Afro-Cuban jazz anthem.

Tin Tin Deo in A#

A# (Bb) major requires barre chords rooted at fret 1 on the A string or fret 6 on the E string. Despite the barre demands, it is a common key in funk, New Orleans R&B, and brass band music. The open D string can ring as the major third for added color. A# is a intermediate-level key on guitar because the open D string is the major 3rd of Bb, adding a bright color if allowed to ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

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

Scales for Improvisation

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