[1] The release of Patricia Hall's sketch-based study of composer Alban Berg's first opera Wozzeck, fifteen years after her earlier parallel study of Berg's second opera Lulu (Hall 1996, awarded the ASCAP Deems Taylor Award), is a seminal event in Berg scholarship. I have previously defined three stages in Berg research (Headlam 1993). The first encompasses writings of Berg himself and his circle of students and correspondents, notably Willi Reich and Theodor W. Adorno. The second stage begins with the writings of Hans Redlich in the 1950s and extends through seminal studies of individual works and overviews of Berg's oeuvre by writers such as George Perle, Mark DeVoto, and Douglas Jarman in the 1970s and 80s. This stage also includes the onset of comprehensive studies of sketches and other materials, and the revelations of the secret programs in Berg's music. The third stage is a continuation and expansion of the directions in the second; it includes my own book (Headlam 1996), Hall's Lulu book (Hall 1996), exegeses of further secret programs in the Chamber Concerto, Violin Concerto and other works, and a number of collected and individual volumes on Berg's music. (1) Hall's present book and the passing of George Perle (January 2009) may turn out to mark the completion of this third stage. In this review, I will consider Hall's book in this context and try to frame some questions that might set the stage for the next generation, which should properly provide a complete biography of Berg as well as new directions for analysis.[2] In her Wozzeck study, Patricia Hall deploys the exemplary sketch and analytical techniques evident in her earlier book. Hall is the undisputed English-language expert on the Berg sketch and biographical material, and this welcome second volume offers the same high level of scholarship and insight into the working methods of this fascinating composer familiar from the first study on Lulu. Readers will come away impressed by the detailed analytical nature of Berg's compositional method, and by the thorough and self-conscious way in which he approached musical and related dramatic questions. Berg was a careful analyst of his own and others' music, and the notes and letters surrounding his first opera confirm that he was sensitive to subtle dramatic and formal points and all aspects of musical and text combinations; his notations characterizing the psychological aspects of Schoenberg's orchestration in Erwartung provide further evidence of this propensity (see pages 103-7). Berg's analytical and communicative abilities are exemplified in the famous lecture presented before some performances of Wozzeck in the 1920s, as well as in several analytical letters to Schoenberg.
