Caravan in Re
Caravan in Re
Ellington and Tizol's exotic minor piece is defined by Phrygian Dominant color on the pedal-point introduction, Harmonic Minor logic in the chord resolutions, and Half-Whole Diminished symmetry over the passing diminished chords. The Spanish-Moorish atmosphere demands a commitment to outside-the-box scale choices that most standards don't require. One of the most harmonically distinctive pieces in the entire jazz canon.

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 D to G (ascending perfect fourth), G to G (ascending unison), G to C (ascending perfect fourth), C to F (ascending perfect fourth), F to A# (ascending perfect fourth), A# to A (descending half step). 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 D by perfect fourth.
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.
