Chord Diagrams — Well You Needn't in B (Guitar)

Well You Needn't in B

Monk's angular composition built on alternating half-step dominant chords (F7-Gb7), creating his signature dissonant yet swinging sound.

Well You Needn't 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 C (ascending half step), C to D (ascending whole step), D to C# (descending half step), C# to C# (ascending unison), C# to F# (ascending perfect fourth). A half-step bass movement creates a strong leading-tone pull that demands resolution. The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from F# to B 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. Over dominant seventh chords, B Mixolydian adds the flat seventh for an authentic blues-rock edge.
