This time using speeds in ratios 7 : 5 : 3, and over a I-VI-ii-V in Eb major.
The metronome coincides with the slowest pulsation throughout the modulations.
The permutations of the three ratios throughout this recording are:
7 7 5 7 7
5 3 3 3 5
3 5 7 5 3
For what it's worth, I always hear the pulsation lowest in pitch as the primary pulse; that it, the "beat."
