Introduction to the essays

Since the inception of this project in 2000 I have added new texts to this site over the years, until it has grown to its current form.

These texts address musicians and general listeners likewise. The essays are mainly the result of just listening (and studying the informative CD booklets of course), and closely observing what the music I heard told me. They intend to raise interest in the works from any potential listeners, listeners with either advanced or basic musical background, and they intend to facilitate listening once the music is experienced. The texts are addressed to all music lovers; all are invited to listen to Stockhausen's music and enjoy its greatness.

I am deeply satisfied and excited to experience that the later output of Stockhausen, up to the end of his career, continued the amazing quality and innovativeness of his well-known classics, and that works like ENGEL-PROZESSIONEN and LICHT-BILDER are not only among the very best of the music of the last 50 years but also among the best music ever written. I truly mean it, while I dearly love the music of Bach, Haydn, Beethoven, Bruckner, Stravinsky, Bartok and so many others before, in between and after. My essays on these and other more recent works – including electronic ones – therefore were a great pleasure to write, as were the others.

What amazes me is that Stockhausen not only continued to write fantastic music until the end, but that he also kept creating new sound worlds with every new work. Stockhausen did not repeat himself or others, settling into a "style", but instead continued to always create new excitement in unique sonic textures. That during his long career as a composer he always managed to do that according to his motto, which he formulated with KREUZSPIEL from 1951, amounts to a staggering lifetime achievement.

The music is all at Stockhausen-Verlag to be acquired, CDs and scores. No worry about deletions of works from the CD catalog (to how many frustrations these can lead with other composers I do not need to tell anybody) – Stockhausen's output can be heard practically in its entirety. Only few of the works have not been recorded thus far.

A number of works are also available in other performances on CD or on streaming services. YouTube provides access to recordings as well, even though in lesser sound quality due to a compressed digital audio format (compressed audio is also used on several other streaming platforms such as Spotify). Access to dynamic visuals on some YouTube links of Stockhausen’s music obviously is a welcome expansion.

Many thanks to Kathinka Pasveer, a close collaborator of Stockhausen, for taking the time to read the "Introduction to Stockhausen", my first six essays (Gruppen, Carré, Mixtur, Ylem, Montag aus Licht, Welt-Parlament), the essay on TIERKREIS (Trio version) and, after 2007, several other essays, including the texts on KATHINKAs GESANG. Some revisions were made by me according to her comments.

I am especially grateful to Stockhausen for his interest shown by reading all my other texts until he passed away in 2007, a generosity very much appreciated in my quest for musical accuracy. I incorporated minor corrections or additions suggested by the composer. I thank both Stockhausen and Kathinka Pasveer for answering several specific questions regarding the music.

Many thanks also to Jerome Kohl, music theorist and a leading expert on Stockhausen with long experience as managing editor of Perspectives of New Music, for editing my texts on HYMNEN, HARLEKIN, DER JAHRESLAUF, WELTRAUM, as well as most of the texts on SAMSTAG aus LICHT, and for numerous invaluable musical discussions.

All older texts were edited in 2005 by me for language and style. Novel information on the form of MOMENTE and KURZWELLEN, which the composer communicated in letters to me, was quoted and incorporated into the respective texts. Other than this, content was not changed, with a handful of minor exceptions.

I hope that these texts convey my genuine enthusiasm for Stockhausen's music, and I wish that this enthusiasm may be reflected, at least to some extent, in the reader's listening experience.
