The 8 bars

Same shape, slid down a whole step each time the chord changes - that's the whole trick here.

Scales to hang the pattern on

Bridge notes: G, A, and D sit in both scales - if the fast switch ever catches you off guard mid-phrase, landing on one of those three always sounds right no matter which chord is under you.

Phrase ideas

2-bar phrases over Em9 -> Dm7, built from the two pentatonic scales above. The first four are straightforward eighth-note bounce; the last three (5-7) add rests, off-beat syncopation, and an anticipated tie across the barline - that gold note at the end of bar 1 in "Push into the change" is Dm7's root, played early and held over.

16-bar roadmap

How a full solo over two passes of the 8-bar vamp can be built from one motif: state it, repeat it, vary it, build tension, peak, then release. Each step below reuses a phrase from above.

How to practice this

1. 1Loop the 8 bars slow with the metronome above (try 70-80 BPM first), playing the fixed E-G-A-B / D-F-G-A pattern until the whole-step drop feels automatic in your fingers, not something you have to think about.
2. 2Once that's solid, keep the fixed pattern but vary the rhythm - try it in eighth notes, or reorder the four notes, while the chord-to-chord motion stays the same.
3. 3Start trading: play the fixed pattern on the Em9 bar, then improvise freely on the Dm7 bar (or vice versa) - the fixed shape becomes your safety net if you lose the thread mid-solo.
4. 4Bring the tempo up gradually toward your real performance speed, checking it against the reference recording below.

Reference recording

This one's confirmed alto-sax-friendly and around 128 BPM. Its own chord voicings wander a bit more (Em, Dm, Em9, Dm7 mixed) than our fixed two-chord chart - that's just the performer's phrasing; stick with Em9 -> Dm7 for your actual part.
