This is the second of a two-volume study of the music of Johann Sebastian Bach. Taking into account the vast increase in our knowledge of the composer due to the Bach scholarship of the last sixty years, Richard Jones presents a vivid and in some respects radically new picture of his creative development during the Coethen (1717-23) and Leipzig years (1723-50). The approach is, as far as possible, chronological and analytical, but the author has also tried tomake the book readable so that it may be accessible to music lovers and amateur performers as well as to students, scholars, and professional musicians. There are many good biographies of Bach, but this is the first, fully-comprehensive, in-depth study of his music making it indispensable for those who wantto study specific pieces or learn how he developed as a composer.
