How Long Has This Been Going On? 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 F# to F# (ascending unison), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to B (ascending whole step), B to D (ascending minor third), D to C# (descending half step), C# to E (ascending minor third), E to D# (descending half step), D# to B (descending major third), B to A# (descending half step), A# to A# (ascending unison), A# to A# (ascending unison). 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 A# to F# by major third.
