Bach traces the man's emergence as a startlingly original organist and composer, describing his creative evolution, professional career, and family life from contemporary societal and cultural perspectives in early modern Europe. His experiences as student, music director, and teacher are examined alongside the music he produced in each of these roles, including early compositions for keyboard instruments, the great organ and harpsichord works of later years, vocal music, and other famous instrumental works, including the Brandenburg Concertos. Schulenberg also illuminates how Bach incorporated his contemporary environment into his work: he responded to music by other composers, to his audiences and employment conditions, and to developments in poetry, theology, and even the sciences. The author focuses on Bach's evolution as a composer by ultimately recognizing "Bach's world" in the specific cities, courts, and environments within and for which he composed. Dispensing with biographical minutiae and more closely examining the interplay between his life and his music, Bach presents a unique, grounded, and refreshing new framing of a brilliant composer.
