@ Michael Sayers. . . .
p.s. for themeandvariation - One reason that I thought it was inappropriate to criticise David for any asynchronicity of hands relates, and for which reason stevensk's post would have been about me rather than David, is a research study done many years ago of the recorded pianists born in the 19th century. It is revealed there that one of the pianists in particular, when he first heard a recording of himself, was astonished to realize that he had been playing one hand before the other. He had been doing this unconsciously, presumably throughout his career.
Criticizing David for this may very well be akin to criticizing a painter for how he holds a brush.
Of course, I know I often play one hand before the other, and have acknowledged this in the threads here: this technique of pianistic expression is, with me, on the conscious level.
So, on a side note when discussions crop up of the composers' intentions, maybe for instance Chopin played one hand before the other unconsciously, and therefore he didn't in fact intend it either way? And maybe Brahms rolled the chords in his own music unconsciously? At first the latter may seem to be a bit of stretch, yet if everyone really was doing these things back then, then perhaps it is possible. One can consider research of various societies which did not have words for particular colours. The eyes could see them technically, but the minds did not distinguish because it wasn't happening at a conscious level of processing - at least, this is the conclusion of that research.
One's mind is - or can be - highly selective in what it hears and sees, it would seem.
