Thank you for taking the trouble to listen and for your generous comments. I have always felt that rhythm, including its subset of phrasing, is intuitively the most important aspect of music. Or to put it another way, the absence of a feeling for rhythm is the omission I find myself least able to understand or accommodate in a pianist, classical, jazz or otherwise. And yet the combination occurs so often: brilliant technique, wonderful memory, perhaps an incredible ear for other things, but without the slightest feeling for rhythm on any deep level. I can only conjecture that it is because, unlike harmony for instance, rhythm cannot be analysed, or at least what limited analysis can be done imparts no feeling for it. Secondly, and again in contrast to harmony, notation is a poor approximation to all but the very simplest rhythms.
It is an ongoing mystery to me why discussion among jazz pianists focuses almost exclusively on arguing about various successions of complicated chords. It isn't as noticeable on this forum, but on Pianoworld such analytical threads, sometimes very heated and tedious, can go on for pages. This is why I have never claimed to be a "jazz pianist", having clearly missed the bus altogether in this respect. I am as fond of fine harmony as the next man but to improvise with nothing else in mind ? I don't think so !
Now the points you draw attention to regarding what the left and right hands are doing are really interesting, far from simple, and contain a little enigma I have not yet solved. In recent years I tend to "think", if that's the right word, through both hands at once. Either hand does duty anywhere on the keyboard as required on impulse, not hesitating to cross both ways for as long as necessary. So except for obvious extremes perhaps, I am never sure when listening to my own playing exactly which hand is doing what. Moreover, at special moments, not I think in this particular example though, I get a wonderful illusion that three, sometimes four event streams - I don't just mean contrapuntal melodies - are progressing simultaneously. I dearly wish I knew how I produce this orchestral effect as I like it very much. But because I forget my improvisation very quickly, never mind the convoluted physical processes going on, it is still a mystery to me.
