I’ve just found this fantastic site offering free classical piano music downloads.
It offers a place for amateur and professional pianists to share their music and performances, and povides free music for the masses (that’s us!)
The Piano Society requires free registration which takes about 30 seconds, after which you’ll have access to the complete library, and information about the composers and pianists.
I listened to a few Chopin pieces and the qaulity, whilst variable, is generally high.
So if you’re after some free piano music, give the site a try.
