Body And Soul in B
Body And Soul in B — immortalized by Coleman Hawkins, famous for its enharmonic modulation to the tritone key in the bridge. Lydian Dominant colors the bridge dominants; Bebop Major rules the outer sections. Changes: C#m7 – G#7b9 – C7 – BMaj7 – E7 – D#m7 – Ddim7 – A#m7b5 – D#7 – G#m7 – C#7 – F#7 – B6 – G#7 – B – G7 – CMaj7 – Dm7 – Fm7 – A#7 – Em7 – Am7 – Cm7 – F7 – A#Maj7 – C#dim7 – A7.
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 G# (descending perfect fourth), G# to C (ascending major third), C to B (descending half step), B to E (ascending perfect fourth), E to D# (descending half step), D# to D (descending half step), D to A# (descending major third), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to G# (descending minor third), G# to B (ascending minor third), B to G (descending major third), G to C (ascending perfect fourth), C to D (ascending whole step), D to F (ascending minor third), F to A# (ascending perfect fourth), A# to E (ascending tritone), E to A (ascending perfect fourth), A to C (ascending minor third), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to C# (ascending minor third), C# to A (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 A to C# 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.
