Internationally recognized Bach authority Hans-Joachim Schulze authored a 225-part series on the cantatas of Johann Sebastian Bach. In this collection, James A. Brokaw II translates a selection of the essays, illuminating a wide range of biographical and cultural features of Bach’s life and creative milieu. Schulze’s lively and engaging discussions provide a wealth of rewarding insights and perspectives focusing on individual cantatas, their texts, and the questions of chronology and context that attend them. The University of Illinois Press has paired the volume with a special web-based companion overseen by the translator and hosted by the Illinois Open Publishing Network. This online resource includes Brokaw’s translations of all 225 of Schulze’s essays alongside digital tools for searching, sorting, and bundling the commentaries according to date of composition, position within the liturgical church year sequence, and librettist.
