While Boulez stated on a number of occasions that he had no great interest in teaching or indeed any particular gift for it, he worked nevertheless in the course of his career in a variety of pedagogical contexts. In this chapter, I consider his work as an occasional teacher of composition, with the small number of individual students he accepted in the late 1950s in Paris for private sessions. Second, there is the teaching he transmitted in the body of lectures he delivered primarily at Darmstadt, Harvard and more extensively at the Collège de France. Finally, I explore his arguably more engaged pedagogical work, exemplified by the courses in analysis, composition and conducting he delivered in Basel in the 1960s, as well as his committed interaction with young composers, conductors and performers at the Lucerne Festival Academy from 2003 to 2015.

A legacy is something inherited by a successor, and in Boulez’s case what he handed down to posterity (his writings, activities and compositions) evolved in complex ways from his own early mentors and influences, particularly Messiaen, along with what the young Boulez determined to be the essential innovations in works that had the greatest unfulfilled potential in the 1940s and early 1950s. Boulez’s own works were naturally part of his legacy but in his later years changes in musical fashion meant that his accomplishments as conductor, writer, teacher of performers and institutional figurehead provided an even more potent example to potential emulators than his actual compositions. His unambiguously modernist sensibility and concern to place serious music at the heart of the prevailing culture brought a remarkable coherence to bear on the rich diversity of his life and work.

This chapter considers Britten’s unique position in the sometimes unstable history of English opera. While acknowledging his central significance as the composer who (almost) single-handedly revived its fortunes with the instant and phenomenal success of Peter Grimes in 1945, it offers a nuanced assessment that views his achievements as part of a much broader picture in which the genre was arguably never as moribund as traditional accounts (and those perpetuated by Britten himself) might suggest. After surveying the riches of the courtly masque and the stage works of Henry Purcell, Italian baroque opera in London, and the surprisingly healthy state of English-language opera in the nineteenth century, the chapter provides a concise overview of Britten’s steady output of operas post-Grimes and his wider significance as a canny entrepreneur who promoted the genre widely – and indeed internationally – at the helm of the English Opera Group.
