I have a certain agenda in mind. I am *really* happy with the full (18m) improvisation, but it goes without saying that a home recording during circumstances so unavoidably unfavourable through global events that I can't even get the instrument tuned doesn't do the improvisation full justice as a musical entity. Swings and roundabouts. Would I have improvised something I am so partial to under "recording" or live performance situations? Maybe, but really I can't guarantee it.9
So.. at the end of the day, a full score will enable me to perform it as a finished composition should live recitals return, or even to record it under studio conditions. I don't know, philosophically, if it will necessarily have the same immediacy when it becomes "interpreted" as opposed to improvised, but I feel it would have a lot of power in a concert hall situation.
En passant, movement two, which has been written out in entirety, not absolutely perfectly but to the point where it should serve as a basis for future performance:
I'm taking my time and care over this because, as both of you clearly realise, this is a major undertaking. Addressing quantum's point, in a sense I am happier writing it out in a dual composer/transcriber role because in a way it is more comfortable to write it out, where ambiguity exists, as "this is clearly what was meant, compositionally" (and, to be clear, I do feel my role as improviser is one of real-time composition) rather than an attempt at a pedantic rendering. I dread those moments of notational and metrical irregularity though - I think editorially resolving them satisfactorily costs the most time.
One plus is I know what figurations my hands naturally gravitate towards!
