In a Sentimental Mood

In a Sentimental Mood in G#

In a Sentimental Mood in G#: Ellington's ballad moves between minor and major with aching beauty, favoring Dorian over minor chords and Melodic Minor over the tonic. Harmonic Minor colors the cadential V7 moments. Chords: G#m – G#mMaj7 – G#m7 – G#m6 – C#m – C#mMaj7 – C#m7 – A#m7b5 – D#7 – G#7 – F#7b9 – Bmaj7 – B6 – Am7 – D7 – Gmaj7 – Em7 – G6 – E7#5 – A7 – F#7.

Key of G#

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 G# (ascending unison), G# to G# (ascending unison), G# to G# (ascending unison), G# to C# (ascending perfect fourth), C# to C# (ascending unison), C# to C# (ascending unison), C# to A# (descending minor third), A# to D# (ascending perfect fourth), D# to G# (ascending perfect fourth), G# to F# (descending whole step), F# to B (ascending perfect fourth), B to B (ascending unison), B to A (descending whole step), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to E (descending minor third), E to G (ascending minor third), G to E (descending minor third), E to A (ascending perfect fourth), A to F# (descending minor 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 F# to G# by whole step.

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.
