Waltz For Debby in Sol#

Waltz for Debby in G#: 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: G#Maj7 – Fm7 – A#m7 – D#7 – Cm7 – F7 – C#Maj7.

Waltz For Debby in Sol#

G# major (or Ab) lives at fret 4 on the low E string. All chords require barre technique, making it less common in guitar-centric songwriting but standard in piano-driven pop. Guitarists often use a capo to access friendlier shapes. G# is a intermediate-advanced-level key on guitar because the open G string is a half step below the root, creating dissonance — avoid letting it ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

The bass line moves through G# to F (descending minor third), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to C (descending minor third), C to F (ascending perfect fourth), F to C# (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 C# to G# by perfect fourth.

Scales for Improvisation

G# 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, G# Mixolydian adds the flat seventh for an authentic blues-rock edge.
