This second edition of Reblitz's title can be used by students and hobbyists, but it's the professional most likely to include this in a personal reference library. Here is all the information essential to the art of restoring and maintaining a piano; from minor repairs and cleaning to major tuning and complete restoration techniques. A fine, specific reference.  --Midwest Book Review
