Ruby, My Dear in A#

Key of 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 G# to D# (descending perfect fourth), D# to C# (descending whole step), C# to A# (descending minor third), A# to F (descending perfect fourth), F to G (ascending whole step), G to F# (descending half step), F# to D# (descending minor third), D# to C# (descending whole step), C# to G# (descending perfect fourth), G# to D# (descending perfect fourth), D# to A# (descending perfect fourth), A# to F# (descending major third), F# to G (ascending half step), G to G# (ascending half step), G# to A (ascending half step), A to D (ascending perfect fourth), D to E (ascending whole step), E to G (ascending minor third), G to D (descending perfect fourth), D to A (descending perfect fourth), A to A (ascending unison), A to G# (descending half step), G# to A# (ascending whole step), A# to C (ascending whole step), C to C# (ascending half step), C# to C# (ascending unison), C# to F# (ascending perfect fourth), F# to G (ascending half step), G to A (ascending whole step), A to E (descending perfect fourth), E to G# (ascending major third). 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 G# by unison.

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.
