Let's Do It (Let's Fall In Love) 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 C (ascending half step), C to C# (ascending half step), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to E (ascending unison), E to A (ascending perfect fourth), A to D# (ascending tritone), D# to G# (ascending perfect fourth), G# to D# (descending perfect fourth), D# to C# (descending whole step), C# to F# (ascending perfect fourth), F# to E (descending whole step), E to G# (ascending major third), G# to E (descending major third), E to C# (descending minor third), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to B (descending minor third), B to G# (descending minor third), G# to F# (descending whole step), F# to G# (ascending whole 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 G# to B by minor 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.
