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