In A Sentimental Mood in D

In A Sentimental Mood in D

One of Ellington's most beloved ballads, featuring a descending chromatic line in the A section and a lush bridge that modulates to Db major.

In A Sentimental Mood in D

D major is one of guitar's most resonant keys. The open D string acts as a droning root, and the open A string provides the fifth. This gives D-based strumming a wide, ringing quality that flatpicks and fingerpicks love. D is a beginner-level key on guitar because the open D and A strings provide a powerful bass foundation, and the open high E is the 2nd scale degree adding brightness. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through B to B (ascending unison), B to B (ascending unison), B to B (ascending unison), B to E (ascending perfect fourth), E to E (ascending unison), E to E (ascending unison), E to F# (ascending whole step), F# to B (ascending perfect fourth), B to D# (ascending major third), D# to D (descending half step), D to A# (descending major third), A# to G (descending minor third), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to G (ascending whole step), G to C (ascending perfect fourth), C to A (descending minor third). A half-step bass movement creates a strong leading-tone pull that demands resolution. 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 A to B 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.
