Or: Preaching to the unconverted.
I think the first thing to say about Kurtág is that he is, by the standards of many favourites of these boards, quite a conventional composer. By which I mean that he's not trying to rewrite the rulebook on anything: he sits quite comfortably within a compositional tradition (something like Beethoven-Schumann-Bartók), rather than attempting to be avant garde.
But it's what he does with that tradition that is where it gets interesting. He's very much a pitch-based composer, and his contrapuntal and harmonic senses are very finely tuned. He has a knack for putting notes together, horizontally and vertically, whereby they can suggest much more than they say. Even if his materials are very often borrowed - from himself, from other composers, or 'objets trouvés' that are so banal as to belong to no one - he tweaks them just enough to retain their identity and make them his own. So there's the constant presence of musical history - often really big, canonical music history - throughout his music, alongside a laying-out of the barest fundamentals of music (see the C major scales of
...quasi una fantasia..., eg), such that you start to lose sight of which is which, and which is him.
The connections aren't just in the music, of course, but very often laid over the top too, in titles, subtitles and dedications, all of which are rarely innocent of any association you can pin to them.
And then there are the performance requirements: a lot of compositional effort is channeled towards making the performances just slightly awkward (hands unnecessarily crossing at the keyboard, wide vocal melismas suddenly exposed), forcing the performer's self-awareness. As the listener needs to do too, the performer also has to bring to the music a broad knowledge of performance practice (the
marcato a la Kocsis direction), and the ability to play something with the feeling of one thing, even if it's written as something else ('waltzes' that are written two-to-a-bar). And don't forget Kurtág's notoriously demanding reputation as an instrumental teacher
This all piles up, pushing the music towards an unattainable ideal, in which 500 years-worth of music history has to be forced through a single note, the single action of a performer - and heard as such. It's knife-edge stuff, and leads to a red raw intimacy in the music. It feels confessional, almost to the point of embarrassing; I find it extremely highly charged, even erotic at times. It's not always comfortable -
Samuel Beckett: What is the Word, for example, is a very troubling piece - but it is always very powerful. That said, it's not something I can deal with in large doses -
Kafka-Fragmente is just too much for me, it's unrelenting.
That was a bit of a gush, sorry - any one else got any thoughts
