Mood Indigo in Re#
Mood Indigo in Re#
Ellington's melancholic ballad weaves Mixolydian dominant color through its signature voicings, with Blues scale phrasing adding emotional weight and Bebop Major lines providing forward melodic momentum. The distinctive three-voice low-register texture in the melody is one of jazz's most recognizable sonic signatures. Slow, deliberate phrasing and tonal beauty matter more here than harmonic complexity.

D# major (Eb) requires barre shapes rooted on the 6th and 5th strings. It is a favorite key for horn players, so guitarists encounter it in funk and soul bands. Using barre chords at frets 1, 3, and 6 covers the primary shapes. D# is a intermediate-advanced-level key on guitar because no standard open strings match this key's chord tones. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.
Voice Leading
The bass line moves through D# to F (ascending whole step), F to A# (ascending perfect fourth), A# to D# (ascending perfect fourth), D# to D# (ascending unison), D# to G# (ascending perfect fourth), G# to G# (ascending unison), G# to C (ascending major third), C to F (ascending perfect fourth), F to F (ascending unison). 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 D# by whole step.
Scales for Improvisation
D# 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, D# Mixolydian adds the flat seventh for an authentic blues-rock edge.
