When I was composing this piece, here's what I had in mind:
I envisioned a waltz scene held inside Canterlot Castle.
The introduction shows m5 making their entrances one after another. Since there are four similar musical phrases, you can let any two ponies you like enter together, while the remaining ponies enter individually.
The exposition features m6 dancing; the development section depicts m6 resting on the side and admiring the grand scene of the banquet.
The recapitulation is the phase of free dance invitations, and the coda is the curtain call, with everyone exiting one after another.
