Ruby, My Dear in B

Key of B

B major mixes barre and open elements. The B chord itself is a barre at fret 2, but E and A are comfortable open chords forming the IV and V. The open B string rings as the root, allowing creative drone-based arrangements. B is a intermediate-level key on guitar because the open B string rings as the root and the open E strings provide the 4th — useful for sus4 voicings and drone effects. This key mixes open and barre shapes, making it a good intermediate challenge that builds fretboard fluency.

Voice Leading

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