durchhaltevermögen was written for Mieko Kanno over about six months beginning late 2016. It is dedicated to the composer, violinist, and improvisor Malcolm Goldstein. Mieko and I share an enormous respect and admiration for Mr. Goldstein's music and his impact on contemporary violin playing. Speaking personally, his improvisations both in live and recorded form have offered me some of the most profound and moving experiences not just of late but of my whole life. I'm very grateful for his music.
But how strange to write a highly detailed composition and dedicate it to a master improvisor. Was I transcribing an improvisation and calling it my own? (Certainly not.) Was I trying to "capture the spirit" of an improvisation? (No. Not really.) Was I trying to capture anything? (No. Release something rather than capture it.) So what's the connection? (The spirit (I hope) and some of the playing techniques.)
The title can be translated from the German as stamina, staying power, or power of endurance. More appealing is the clumsy-literal translation of this compound noun's three units: through-holding-power:
Through as in through-composed: not only is this work in one continuous movement but it lacks, in its raw construction at least, formal sectional variety or opposition. Through also as in the biblical (via Bergman) through a glass darkly (a poor image or reflection perhaps: (my) humility in the face of (his) genius).
Holding as in supporting (a weight, which takes effort) but also holding back, suspending (which takes a completely different kind of effort). And of course holding a tone, a bow, and pushing through.
Power not in the sense of raw muscle or power over others, but power as in poise, mastery, the power of technical accomplishment, the power of multivalent interpretation; to be able to hold and present seemingly opposing states or views of an object, as in the Catuskoti paradox. (Take for example the question "Is this piece an improvisation?" Catuskoti insists that there are four, not two, possible answers: true, false, true and false, or neither true nor false, with the latter two being surely the most interesting responses.)
durchhaltevermögen was generated with the jitterbug algorithm I developed using my slippery chicken algorithmic composition software. After much tweaking this created a raw form of rhythms and pitches upon which a detailed reading was superimposed (an interpretation, a composer's cut, you might say). Next of course comes the violinist's reading. Then the listener's. (Did I really compose this piece? True? False? True and False? …)
