It's 41i for today, lads.  Let's get down to business!

AABACA was the structure of the thing.  Same impression of the watery undergrowth of the piece, organ-donored, for our apparent delight.  Otherwise, fraid I got nothing to say.  Looks like it's on to the next one...

41j is an AABABA, but even this makes it seem more entertaining than it is.  The B parts are, I'm afraid, not more than weird "startup" intros to the main section, not more than four measures long.  Which makes this runner a catcher with this form: AAAA.  Not exactly the caliber of variation I was expecting.

42a is a sym-phonie.  First partie is a Fast, Majestic.  Good times then, eh?  Who wouldn't want to take a crack from the ladie?  Well, me encanta la tema at the 48 second mark, warm, excited feeling.  It sounds like it could be the beginning of a movement, but it's actually the second to the last mini-theme in theme A.  The large plan for the movement is as follows: AABB.  And here's the interesting thing, friends.  The B begins and end with A. The minor variation of the idea is in the center.  And the bit I liked from the movement?  That part of section A remains in section B and brings the section home after the minor key grazing ground in the smack dab of the B part.  Yah, that's pretty great.  I recommend.  Second part is Andante.  Also AABB.  Pizzacattish, strange.  Neal Zaslaw, of Academy of Ancient Music Fame, calls this portion of the cake an "irritant." Now, on to the Minuetto and Trio.  Arrangement of all this rather hard to pick out (AABA?). Or maybe, more probably, being more sensitive to smaller themes, ABABA'BCC'C???C'ABA'B, the weird chromaticish second or third measure theme that leaps all over the place, jarring so uncomfortably, at least, initially, with the first theme, and so, for that reason, deserving perhaps mini theme treatment.  Many think this portion is too mature for the young Mozart and came later.  In any case, so far, by far the most memorable.  Allegro part here at the end quite pretty, structured like the first two AABB.  This one sticks out the most if the third doesn't belong.  When I first heard this, I thought I had heard it before...All of this typing better not be for something I've already reviewed.

And it turns out...yes, I already reviewed 42a.  Well, nevermind., got considerably more out of it this time.
