Lively, all right; as you said, "corybantic" -- I had to refer to Webster, like, thanks -- and the sound found for your piano (nice one, RM) is perfect for its manic-darting-of-a-part. Percussionings, performancings, designings of sounds, and its all-over splendour in mixings, combine to result in a jolly resounding and uplifting piece. Naturally. FUN. (Can't get enough of the stuff).
