Illustrated with twenty-four black-and-white plates, this volume boasts over a thousand alphabetically arranged entries that cover Bach's music, his life and times, scholarship on Bach, and the performance of his music. Readers will find entries on the various genres that Bach worked in (including chorales, fantasia, sonata, concerto, missa), his many individual works (such as St. John's Passion, The Goldberg Variations, Brandenburg Concertos, Passacaglia, Well-Tempered Clavier, The Christmas Oratorio, and The Art of Fugue), places important to his career (such as Muhlhausen, Weimar, and Leipzig), and important contemporaries (Handel Rameau, Vivaldi, Telemann, among others). There are also entries on instruments (harpsichord, organ, clavier, and so on), Bach performance practice, stylistic influences on his work, and other biographical details. The book concludes with a family tree, a chronology of Bach's life, a list of his works, and a glossary of terms.
