Caroling away

In working away at the Op.126 № 3 on this morning's bus ride, I decided to "re-insert" a variation which I had been thinking of originally. So the rough scheme through to the end is:

 

Var. II — wandering through divers pitch-centers
Var. III — "skeletized" theme plus rapid two-note pick-ups
Var. IV — arpeggiations
Theme — varied return
