Arnold Schoenberg, Arnold Schoenberg, Wassily Kandinsky: Letters, pictures and documents (London: Faber and Faber, 1984)

»In your works, you have realized what I, albeit in uncertain form, have so greatly longed for in music. The independent progress through their own destinies, the independent life of the individual voices in your compositions, is exactly what I am trying to find in my paintings.«

»But as I said, ‘Der gelbe Klang’ pleases me extraordinarily. It is exactly the same as what I have striven for in my ‘Glückliche Hand’, only you go still further than I in the renunciation of any conscious thought, any conventional plot.«
