Bach S Numbers

In the eighteenth century the universal harmony of God's creation and the perfection of the unity (1:1) were philosophically, morally and devotionally significant. Ruth Tatlow employs theoretical evidence and practical demonstrations to explain how and why Bach used numbers in his published compositions.

In 1947 Friedrich Smend published a study claiming that J. S. Bach used a natural-order alphabet (A = 1 to Z = 24) in his works. He demonstrated that Bach incorporated significant words into his music, and provided himself with a symbolic compositional theme. Here, Dr Tatlow investigates the plausibility of Smend's claims with new evidence, challenging Smend's conclusions.

This book shows how information theory, probability, statistics, mathematics and personal computers can be applied to the exploration of numbers and proportions in music. It brings the methods of scientific and quantitative thinking to questions like: What are the ways of encoding a message in music and how can we be sure of the correct decoding? How do claims of names hidden in the notes of a score stand up to scientific analysis? How many ways are there of obtaining proportions and are they due to chance? After thoroughly exploring the ways of encoding information in music, the ambiguities of numerical alphabets and the words to be found “hidden” in a score, the book presents a novel way of exploring the proportions in a composition with a purpose-built computer program and gives example results from the application of the techniques. These include information theory, combinatorics, probability, hypothesis testing, Monte Carlo simulation and Bayesian networks, presented in an easily understandable form including their development from ancient history through the life and times of J. S. Bach, making connections between science, philosophy, art, architecture, particle physics, calculating machines and artificial intelligence. For the practitioner the book points out the pitfalls of various psychological fallacies and biases and includes succinct points of guidance for anyone involved in this type of research. This book will be useful to anyone who intends to use a scientific approach to the humanities, particularly music, and will appeal to anyone who is interested in the intersection between the arts and science. With a foreword by Ruth Tatlow (Uppsala University), award winning author of Bach’s Numbers: Compositional Proportion and Significance and Bach and the Riddle of the Number Alphabet. “With this study Alan Shepherd opens a much-needed examination of the wide range of mathematical claims that have been made about J. S. Bach's music, offering both tools and methodological cautions with the potential to help clarify old problems.” Daniel R. Melamed, Professor of Music in Musicology, Indiana University

First published in 1985. A handbook and text for the performance of Bach's music and Baroque music in general, also serving as an assessment of current trends in historical performance practice by an important American practitioner. Newman clearly presents problems and their solutions, with examples and regular assignments throughout. Paper edition (unseen), $32. Annotation copyright by Book News, Inc., Portland, OR

The Ashgate Research Companion to Johann Sebastian Bach provides an indispensable introduction to the Bach research of the past thirty-fifty years. It is not a lexicon providing information on all the major aspects of Bach's life and work, such as the Oxford Composer Companion: J. S. Bach. Nor is it an entry-level research tool aimed at those making a beginning of such studies. The valuable essays presented here are designed for the next level of Bach research and are aimed at masters and doctoral students, as well as others interested in coming to terms with the current state of Bach research. Each author covers three aspects within their specific subject area; firstly, to describe the results of research over the past thirty-fifty years, concentrating on the most significant and controversial, such as: the debate over Smend's NBA edition of the B minor Mass; Blume's conclusions with regard to Bach's religion in the wake of the 'new' chronology; Rifkin's one-to-a-vocal-part interpretation; the rediscovery of the Berlin Singakademie manuscripts in Kiev; the discovery of hitherto unknown manuscripts and documents and the re-evaluation of previously known sources. Secondly, each author provides a critical analysis of current research being undertaken that is exploring new aspects, reinterpreting earlier assumptions, and/or opening-up new methodologies. For example, Martin W. B. Jarvis has suggested that Anna Magdalena Bach composed the cello suites and contributed to other works of her husband - another controversial hypothesis, whose newly proposed forensic methodology requires investigation. On the other hand, research into Bach's knowledge of the Lutheran chorale tradition is currently underway, which is likely to shed more light on the composer's choices and usage of this tradition. Thirdly, each author identifies areas that are still in need of investigation and research.

'What is a self and how can a self come out of inanimate matter?' This is the riddle that drove Douglas Hofstadter to write this extraordinary book. In order to impart his original and personal view on the core mystery of human existence - our intangible sensation of 'I'-ness - Hofstadter defines the playful yet seemingly paradoxical notion of 'strange loop', and explicates this idea using analogies from many disciplines.
