El Cantar Del Coquí 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 D# to A# (descending perfect fourth), A# to D# (ascending perfect fourth), D# to F# (ascending minor third), F# to E (descending whole step), E to B (descending perfect fourth), B to D# (ascending major third), D# to C# (descending whole step), C# to D (ascending half step), D to C# (descending half step), C# to C (descending half step), C to F# (ascending tritone). A half-step bass movement creates a strong leading-tone pull that demands resolution. The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from F# to D# 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. Use the Lydian mode (raised 4th) over the IV chord for a dreamy, floating quality that lifts the harmony.
