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

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.
