This is a do-it-yourself book.
Let the Buyer (that's you) Beware. Ultimately, you are the one who is responsible for what you do with this book. I have tried my best to make it easy to understand, but you can still mess up your piano simply because we do all err. I hope this statement doesn't put you off. I simply feel I have to put it here to define any liabilities. In proceeding to use this book, you agree to take all liability upon yourself. If you are the kind of person who takes responsibility for your own actions, this page does not need to mean one thing to you.
Having said the above, I want to stress that this is the only book of its kind anywhere. If you have any mechanical skills at all, you can save yourself a lot of money by following instructions and improvising a little.
I am available to you if you have problems as you work on your piano:
