Chord Diagrams — Ruby My Dear in A# (Guitar)

Ruby My Dear in A#

One of Monk's most beautiful ballads with cascading chromatic chord pairs, showcasing his tender side beneath the angular exterior.

Ruby My Dear 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 G (descending half step), G to F# (descending half step), F# to F (descending half step), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to D (ascending tritone), D to G (ascending perfect fourth), G to C# (ascending tritone), C# to F# (ascending perfect fourth), F# to C (ascending tritone), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to B (descending major third), B to C (ascending half step), C to F (ascending perfect fourth). 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 A# by perfect fourth.

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.
