Piano Sonata No. 9 in D major, age 21
The official number is K. 311, which was an old attempt to put Mozart’s music in chronological order, but it was a very inaccurate system. The book in which I first saw this sonata put the sonatas in a completely different number. I remember them by key, and there are three sonatas in the key of D major. This is the 2nd and was written late in 1777. The number above, No. 9, is absolutely inaccurate. It seems that every editor numbers these sonatas differently, so pianists generally seem to refer to it as K. 311
Various pianists, in no particular order
This is a very early recording, all the way back to 1937. It is incomplete
These three recordings above are what I first heard. I don’t know why they are broken up this way, which seems stupid.
These other five recordings are all a bit different, and I have not listened to all of them completely.
