Chord Diagrams — Lazy Bird in Si (Guitar)

Lazy Bird in Si

Coltrane's rhythm-changes variant speeds through Dorian and Mixolydian motion with bebop precision in a demanding B setting. The rapid harmonic rhythm rewards players with strong ii-V-I muscle memory and fluid bebop vocabulary. Push the Cm7 – F7 – Bm7 – E7 – AMaj7 – A#m7 – D#7 – G#Maj7 – C#m7 – F#7 – BMaj7 – A#Maj7 – Dm7 – G7 – CMaj7 – Fm7 – A#7 – D#Maj7 changes to develop speed and clarity under the kind of harmonic pressure Coltrane thrived on.

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