Green Is The Colour 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 F# to B (ascending perfect fourth), B to A# (descending half step), A# to D# (ascending perfect fourth), D# to C# (descending whole step). A half-step bass movement creates a strong leading-tone pull that demands resolution. The mix of stepwise and leap motion balances smoothness with harmonic drive. When the progression loops, the bass returns from C# to F# by perfect fourth.
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. Layer in the full major scale for melodic runs, reserving the pentatonic for riff-based phrases.
