Hugh has a very nice piece today on learning the Rackmaninov Third Concerto. It's all about the mental feats, and training the memory in certain ways. There's the sharp focus on difficult passages and refining the fingerwork, working on the glue between sections, and then the drift out, the wide lens shot, where the music flows from beginning to end. It sounds as though the neurons and synapses are getting a full workout in someone's brain, and I'm much happier here typing away, than struggling with hundreds of thousands of notes.
Gieseking would be so proud of Hugh. A pianist's agony here
