Query: Dated and not useful

As other reviewers have stated, this book (published in 1907) is so dated one wonders how it is even still in print. Perhaps the only value is the author teaches you about tuning the piano using the slower beating 4ths and 5ths method (once the main method, aural tuners now predominantly use the faster beating 3rds and 6ths method). However, even this method is explained cumbersomely by the author. The section of repairing piano parts and regulation is anemic and terribly short considering the complexities of a piano. Poor illustrations with an antiquated writing style, this book is best left in the dustbin of piano literature.
