The music

#1, F major, K.37: So what if this is WAM's arrangement of someone else's work. But the first movement —  not WAM's fault — is contemptible in its instability: the syncopation makes it unplayable; at any rate I find that it induces motion sickness. (K.466 works because it starts on the first beat and is stable.) 

#2, Bb Major, K.39: Some improvement. This is a pleasant piece, congenial to play (Bb is a perfect key for it).

#3, D major, K.40:  More indifference, though one can have some fun with the second movement.

#4, G major, K.41:  The first movement is something out of a lunatic asylum. Maybe it's possible to play it attractively. I doubt it. We'll give it a go.

#5, D major, K.175:  WAM's first original. There's real music in it from the outset. The first movement makes a conspicuous ass out of anyone who plays it excitedly. The usual challenge: to forget you have ever heard CBS or Hollywood Bowl Mozart and to play it sedately, elegantly, slowly and quietly. Can you imagine how that sounds? 

#6, Bb major, K.238: Touching, elegant, a pleasure to play. Cf. K.595 and WAM's other Bb major piano concertos.

#8, C major, K.246: I've played this many times in public, increasingly enjoyably (for me at least). I always find something new and fresh in it. Easy to play badly. Highly effective with a string quartet. Ignore all the speed markings.
