I found this book in a public library, flipped through 10-20 pages, and immediately borrowed it. Hope it will give me tips to improve my techniques https://www.amazon.com/Piano-Lessons-Claudio-Arrau-Philosophy/dp/0199924341/ref=sr_1_1?ie=UTF8&qid=1449242210&sr=8-1&keywords=piano+lessons+with+claudio+arrauAlso, there's a companion website to this book.https://global.oup.com/us/companion.websites/9780199924325/
May be yes, may be not... Big question mark at least for me...The author claimed to have worked with these people (which she claimed to be Arrau's pupils), German Diez, Frederick Marvin, Goodwin Sammel, Rosalina Sackstein, Alfonoso Montecino, Ena Bronstein-Barton, Edith Fischer, Ivan Nunez, William Goodrum, Bennett Lerner, Loretta Goldberg, Roberto Euzaguirre, Joseph Ries, Stephen Dury, and Jose Aldaz. Are they really Arrau's pupils?I am a slow reader, and haven't reached the chapters on core technique parts. However, what I was attracted initially was Appendix instead (LOL), which is "Lessons" (with Mario Miranda and Bennett Lerner on works of Chopin, Beethoven, Ravel and Strauss). Not sure if these lessons are also fraudulent...
