Harlequin 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 B to D# (ascending major third), D# to F (ascending whole step), F to D# (descending whole step), D# to F# (ascending minor third), F# to C (ascending tritone), C to D (ascending whole step), D to F# (ascending major third), F# to F# (ascending unison), F# to E (descending whole step), E to B (descending perfect fourth), B to C (ascending half step), C to B (descending half step), B to F (ascending tritone), F to F (ascending unison), F to C# (descending major third), C# to F# (ascending perfect fourth), F# to F# (ascending unison), F# to A (ascending minor third), A to D# (ascending tritone), D# to D# (ascending unison), D# to F (ascending whole step), F to A# (ascending perfect fourth), A# to A# (ascending unison), A# to F (descending perfect fourth), F to B (ascending tritone), B to E (ascending perfect fourth), E to D (descending whole step), D to D (ascending unison), D to B (descending minor third), B to D (ascending minor third), D to G (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 G to B by major third.
Scales for Improvisation
B 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, B Mixolydian adds the flat seventh for an authentic blues-rock edge.
