I always enjoyed playing in Carnegie Hall. Built in 1892 I think it is still one of the best concert halls in the world because one can feel the sympathetic vibrations when playing in it. One of the reasons, I think, is because the structure is mainly of wood, and the stage acts as a sounding board unlike many of the modern halls designed by acoustic “experts” which are dry sounding and not very resonant, maybe because of the over use of concrete and glass.
Great credit must be afforded to Isaac Stern, the violinist, who made it his main work in later life to save the Carnegie Hall. The last time I played with him was at the United Nations on United Nations Day in 1964. He was a fine player, not always consistent in his playing, but nevertheless a great artist.
