This is an AABA form. The chords are almost gypsy like. We play two measures of D minor, then two measures of Bb7 to 2 measures of A7 and back to D minor. The bridge goes to the key of Bb using a 1-6-2-5 progression. We start with an inverted three note arpeggio using the famous Dizzy rhythm from "Night in Tunisia". We're essentially stealing this famous jazz rhythm. When changing chords, we pick out the note that is different in the chord, which is Ab for the Bb7 coming from the A note, which is the 5th of D minor. In the bridge, we use a riff based idea for the whole bridge ending with a lead up scale to the last A section.
