About a year ago I visited the Steinway factory in Hamburg, and on the wall they had a large, coloured poster of well-known pianists over the past 250 years or so. They were arranged as a sort of family tree, with all the main teachers and pupils connected by coloured lines. It was a neat idea, and I wonder whether anyone knows more about it? Where might one buy a copy, for example? I should have asked at the time, of course, but I was in a hurry, and had to catch the train to Berlin.
