I can't enlighten you on any aspect of Wuorinen's work, I'm afraid. This is, in fact, my first listening to anything of his output. I'm intrigued, sometimes mesmerized, but a little bit adrift as to what aspect of the notes I should most particularly be attuned to. Superficially, the language seems to be based on serial technique. How tightly? How loosely? What should my ear search for in the way of organization? I enjoy much of what I hear in this piece, but my attention drifts because I can't find any, well, audible anchor, such as form, recognizable tonal organization or motivic development.
I realize this is only a portion of the piece, so perhaps I'm being unfair to both me and the composer.
At any rate, this is not written in criticism of the composer. I'm the ignoramus. I'm asking how would you educate someone like to me to appreciate this man's work? What are his compositional aims here?
Thanks for any response . . . and for your post of this excerpt.
