This book sets forth the provocative theories of a musician who has been called the outstanding harpsichordist of this century. The late Ralph Kirkpatrick reveals here his approach to a deeper comprehension of music, showing how his methods are applied to the preludes and fugues of the Well-Tempered Clavier of J.S. Bach. "This book is brilliant and important."-Clavier "All keyboardists performing classical repertoire can greatly benefit from Kirkpatrick's scholarship, dry wit, and stubborn dedication."-Keyboard "That Mr. Kirkpatrick's extraordinarily perceptive mind knew the subject matter thoroughly is beyond dispute. . . Valuable insights into the analysis, teaching and performance of all Western music, especially Bach's monumental Well-Tempered Clavier."-Arthur Lawrence, The American Organist "We are fortunate to have this book by Ralph Kirkpatrick. . . From it we gain insight into the musical mind of one of the outstanding performers of our century."-The Music Review "The real matter of the book is good old-fashioned musicianship."-Denis Arnold, London Review of Books
