I'm still a bit ahead on The Lincolnshire Poacher. And it's quite interesting, the lag between it and Dance of the Hours, because it means I can see the learning process in operation. I can read music, but not yet sight read, which means simply that I'm much slower at reading than I need to be for playing. And that in turn means I need to memorize the pieces.
It takes a long time. I've been learning The Poacher for months now. I can see progress now that I'm giving it an hour almost every other day, but it's still not quite memorized, sometimes, less and less each session, I'll momentarily lose the flow. Likewise with Hours. But as those last memory wrinkles get ironed out, I listen more, get the tempo right. It's easier with The Poacher, because I can hear the song in my head, though, disconcertingly, it's in a Benjamin Britten arrangement, - Devin Barad in that link, but I can hear Peter Pears, assassin of trad tunes, singing it. I think Dudley Moore (below) had the last word on that. And it's worth sticking with it for the Kurt Weill.
