On tuning, read this:
" Research in my teens into historic organ tuning, and thence a decade of experiment and research instigated by contemplating Chopin's 2nd Sonata in Bb minor brought a realisation that it's the modern tuning that has robbed us of the differences between the keys, and that it wasn't my ears at all. It seemed as though Chopin was deliberately intending the effect of the key of Bb minor to express the cold wind whistling over the graves and I knew from historic organs that that is what the tuning would do. The colour has been robbed from us and the true meaning of "Chromatic" is so lost to us now that Colour isn't mentioned in the relevant Wikipedia article.
The consequence of this is that our classical music has been reduced in the number of dimensions in which it communicates and that this has led to increasingly mere mechanical performances that don't engage so well emotionally, leading to a degradation in musical appreciation and of its value as emotional communication and literature.
