This is a nice, reasonably priced edition of Mozart's sonatas. It also includes his Fantasies also. My biggest problem is that there are no fingerings present. Yes, the lack of excessive fingerings can sometimes be good, but there are absolutely none given in this edition. There are also some editorial changes, none of which are glaringly severe, but slightly annoying.Mozarts sonatas are a must for any classical pianist and a great teaching tool for the intermediate pianist wishing to advance to more challenging works. The Dover edition is fine, but you might want to examine other editions before settling on this one.
