After Adamy, what was needed, above all, was a book of comparable weight and seriousness on the music itself. And that is what John Williamson had provided in The Music of Hans Pfitzner ... What Williamson has done here, more convincingly than any previous writer, is to bring out the subtle inventiveness of Pfitzner's stylistic experiments in form, harmony and counterpoint. Here at last is a book which can domonstrate that Pfitzner was no mere stylistic reactionary ... the most penetratingly sympathetic study of his music so far.
