Lately, I've been listening to Mozart's complete piano sonatas performed by Andras Schiff on London (443 717-2), and Schiff's new set of Haydn's sonatas on Teldec (0630-17141-2). I think that one of the keys to understanding music is by comparing: same works, different performers; different works, same performers. Now, I only listened to both sets two or three times, and then during my daily commute to and from work. Admittedly, my '85 Accord does not have the best accoustics. However, I have a pretty good sound system and I think I was able hear a few things. I remember Don Satz describing Mozart as an "entertainer." Comparing the Mozart and the Haydn, I agree, at least with regards to the sonatas. They would not be out of place being performed quietly at an expensive restaurant. The outer movements are bright, lively and inventive. However, I find something missing in the slower second movements. It's as if Mozart wrote them merely because they were obligatory. I wonder what Mozart thought of them. They don't sound as if they are "knock-offs" or trifles, but compared with the Haydn, they lack some weight. I think that Haydn used the sonatas as more of a means of expression, rather than to amuse himself. If I was in a restaurant and someone was playing Haydn, my food would probably get cold. I think Haydn wrote his sonatas with more emotion. They are more serious than the Mozart, although I do not think any work of Haydn could ever be without humor. Again, I agree with Don in that these sonatas sound almost Romantic. Schiff is excellent in both. However, I like Schiff's playing of the Haydn more than his playing the Mozart; maybe because Schiff's style is more suited to Haydn; maybe because the Haydn recordings have a clearer sound. I wish I could express myself better. If any other List members have any comments, I would like very much to read them. Thanks, as always. Ron Chaplin
