A lot of practice today. Spent some time this morning with the Minuet, playing it through ten times. And then this evening I sat down at the keyboard and had another ten, but was feeling somewhat minueted-out. So I thought I'd play Lilliburlero for old times' sake, and... I'd forgotten it. I had to dig out the music, and spend I don't know how long getting it back. But it did come back. Memories of the summer in Bedford and the Bluthner where I learned it, and the midi keyboard felt very clumsy by comparison.
Having got Lilliburlero back into the process memory, I went back to the Minuet for a couple of play throughs. I know my process memory is capable of holding the two tunes, but I realised you need to keep playing the repertoire, even if it does only consist of one and a half tunes, as mine does. It's difficult to be objective, but the Minuet playing seemed better, perhaps as a result of shuggling the neurons with Lilliburlero? Anyway, in future I'll give not fixate on one piece again for weeks to the exclusion of all else.
I also did a few G major scales, and was very impressed by how fast I was doing them, without really thinking. Maybe the Minuet is feeding into that skill. I've also had a couple of games on the PianoNotes app. Some progress there.
A good day at the keys. Overall practice stamina is growing, I did at least three hours today, and it's getting more enjoyable.
