13 Fluctuating 2 bar - experiments01

Had a good muck around with some ideas from yesterday's post today. The two bar fluctuating tempo has three convergence points in each bar. I've moved it to 15/16 time signature. The accents in the changing tempo are in groups of 7,3,5, and they align with the 1st, 6th and 9th semiquavers of the steady tempo. Tomorrow the plan is to try and play this on my instrument and see how it feels. Audio and an attempt at some notation for it below. The melody below comes in after about a minute on the soundcloud link.
