By a Waterfall 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 C# to E (ascending minor third), E to G# (ascending major third), G# to F# (descending whole step), F# to A (ascending minor third), A to B (ascending whole step), B to F (ascending tritone), F to D# (descending whole step), D# to G (ascending major third), G to G (ascending unison), G to F# (descending half step), F# to F# (ascending unison), F# to B (ascending perfect fourth), B to C# (ascending whole step), C# to B (descending whole step), B to D# (ascending major third), D# to D# (ascending unison), D# to E (ascending half step), E to E (ascending unison), E to G# (ascending major third), G# to C# (ascending perfect fourth). 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 C# to C# by unison.

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.
