Invitation in B: Bronisław Kaper's mysterious minor standard carries an unsettling harmonic pull. Dorian governs the stable stretches while Lydian Dominant and Altered scales navigate the chromatic dominant motion. Chords: Cm7 – C#7#11 – A#m7 – B7#11 – A7#11 – G#m7 – G#Maj7 – Dm7b5 – G7b9.

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 C# (ascending half step), C# to A# (descending minor third), A# to B (ascending half step), B to A (descending whole step), A to G# (descending half step), G# to G# (ascending unison), G# to D (ascending tritone), D to G (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 G to C 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.
