Waltz For Debby in Si

Waltz for Debby in B: Bill Evans's jazz waltz blossoms through lush upper-structure voicings and subtle harmonic extensions. Bebop Major and Lydian scales trace the major chord color — Dorian enriches the minor ii passages. Chords: BMaj7 – G#m7 – C#m7 – F#7 – D#m7 – G#7 – EMaj7.

Waltz For Debby in Si

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 G# (descending minor third), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to D# (descending minor third), D# to G# (ascending perfect fourth), G# to E (descending major third). 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 E 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.
