Ornithology in B

Ornithology in B: Charlie Parker's bebop head on How High the Moon runs the cycle of fourths with surgical precision. Bebop and Bebop Major scales are the core language — navigate the ii-V-I sequences in multiple keys without hesitation. Chords: BMaj7 – Bm7 – E7 – AMaj7 – Am7 – D7 – G7 – F#7 – Bm – Em7b5 – D#m7 – G#7 – C#m7 – B – C7.

Ornithology 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 B to B (ascending unison), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to A (ascending unison), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to F# (descending half step), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to D# (descending half step), D# to G# (ascending perfect fourth), G# to C# (ascending perfect fourth), C# to B (descending whole step), B to C (ascending half 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 C to B by half 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.
