Timbre Melody

I have become rather obsessed with this piece. Particularily the opening (until about 2:00), beyond that it I loose interest as the flurry of pitches get in the way for me. I am thinking that the opening melody is played out through several times, then after 2:00 what had been long tones using breath and the space between notes for the compositional form in the begining is articulated with pitch.
