Teachers and flutists at all levels have praised Nancy Toff'sThe Flute Book, a unique one-stop guide to the flute and its music. Organized into four main parts--The Instrument, Performance, The Music, and Repertoire Catalog--the book begins with a description of the instrument and its making, offers information on choosing and caring for a flute, sketches a history of the flute, and discusses differences between members of the flute family. In the Performance section, readers learn about breathing, tone, vibrato, articulation, technique, style, performing, and recording. In the extensive analysis of flute literature that follows, Toff places individual pieces in historical context. The book ends with a comprehensive catalog of solo and chamber repertoire, and includes appendices with fingering charts as well as lists of current flute manufacturers, repair shops, sources for flute music and books, and flute clubs and related organizations worldwide. In this Third Edition, Toff has updated the book to reflect technology's advancements--like new digital recording technology and recordings' more prevalent online availability--over the last decade. She has also accounted for new scholarship on baroque literature; recent developments such as the contrabass flute, quarter-tone flute, and various manufacturing refinements and experiments; consumers' purchase prices for flutes; and a thoroughly updated repertoire catalog and appendices.
This volume gives an overview of the recent representative developments in relativistic and non-relativistic quantum theory, which are related to the application of various mathematical notions of various symmetries. These notions are centered upon groups, algebras and their generalizations, and are applied in interaction with topology, differential geometry, functional analysis and related fields. The emphasis is on results in the following areas: foundation of quantum physics, quantization methods, nonlinear quantum mechanics, algebraic quantum field theory, gauge and string theories, discrete spaces, quantum groups and generalized symmetries.
