Mood Indigo in Do
Mood Indigo in Do
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.

With no sharps or flats, C major is the theoretical home base on guitar. The open G, B, and high E strings all belong to the C major chord, creating natural sustain. C is a beginner-level key on guitar because the open B and high E strings ring within the scale, and every basic chord uses familiar open shapes. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through C to D (ascending whole step), D to G (ascending perfect fourth), G to C (ascending perfect fourth), C to C (ascending unison), C to F (ascending perfect fourth), F to F (ascending unison), F to A (ascending major third), A to D (ascending perfect fourth), D to D (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 D to C by whole step.
Scales for Improvisation
C 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, C Mixolydian adds the flat seventh for an authentic blues-rock edge.
