When I play the piano, I will just start doodling and see where
   it comes. I like to play very fast and lots of arpeggios and
   sometimes I smash the lower keys with octaves; going to
   different keys and such. It's improvisational, although there
   are patterns, and I don't what the style is; never figured it
   out. Anyway, as the player, *I don't know* what's coming next as
   I'm playing; it just... comes. I always have my mind on the
   resolution as I play - not knowing what it is, but knowing that,
   at some point, the song will temporarily end. [but I can pick
   the 'theme' up again later, continuing the song after, say, 5
   years of pause, if I like) - but that temporary ending is in
   mind somewhere as I play, as I can stop the song anytime I want
   to. When I notice patterns I'm following, either of chords or
   style, I try to break the pattern, unless it's a pattern I don't
   particularly mind. Cause and Effect are a wonky, tricky thing to
   determine. They intermingle, because the ultimate effect (the
   end of the song), while unknown, is a known and it
   back-influences the present, while the past also affects what
   I'm playing. But Time isn't liinear. It skips around, goes
   backwards, inverts at least in the context of improvisation. As
   far as "reality" goes, I have no reason to believe that reality
   doesn't also work in the same fashion. If it works in this
   microcosm, no reason it couldn't work in a macrocosm, as it
   were, just not everywhere perhaps.
