  Dan, 
 
From hanging about with you, I'd say it was because four flats was an 
illegal key for clarinet writing at the time. Is this the only case of 
Mozart writing in this key, or did he ever use the four flat key signature? 
 
He had the right idea. I think it still should be illegal :-). 
 
The broadcast is great. I have not listened to the concerto yet, just to Non 
Piu di Fiori. Awesome! A beautiful sound. It is interesting that one can 
tell where the cross fingerings occur on the period basset horn.

<snip> 
The clarinet problem is that in the first 30 measures for the clarinets, 
Mozart deliberately writes for the instruments in the wrong key.  That's 
correct.  He does it wrong on purpose. And I've checked the manuscript in 
Mozart's hand (a copy of which I own, so we talking about the straight 
skinny here), and that's the way it is in the autograph, I assure you. 
 
So here are the facts and then a question or two for the curious among you. 
 
The overture to the opera is in the key of concert d minor. For this key, 
Mozart explicitly calls for a pair of A clarinets. What this means is that 
the key signature of the first twenty measures should be that of f minor or 
FOUR FLATS. 
 
So why does Mozart write the clarinet parts in one flat? Not only is it the 
wrong key, but he must personally write flats for e, a, and d in order to 
get the other normally flatted notes played correctly.  So in the very first 
measure, he flats the a of the second clarinet. And he also has to juggle 
the accidentals by hand for either the first or second clarinet (or both) 
for measures 19, 20, 25, 27, 28, and 29.  That is, if he had written the 
part using the correct key of four flats for the A clarinets, he would not 
have needed to add those otherwise unnecessary accidentals; i.e., those 
notes would have been flatted by virtue of the key signature. 
 
At measure 31 of the overture, the work slips from concert d minor to 
concert d major and the A clarinets are happily left in the key of one 
written flat which is exactly what they need for a piece in concert D major. 
 
So the question to the list is this: why did Mozart deliberately write in 
the wrong key for a pair of A clarinets for 30 full measures?? (And as an 
ancillary question, why did he not use a B-flat or C clarinet in the 
overture? Why was he almost compelled to call for A clarinets which he then 
wrote for in the wrong key for 30 measures?)
