say, i happened to see on amazon a book entitled 'debussy in proportion.' it looked like interesting reading. u can read excerpts online. i never really thought debussy was interested in proportion per se - but simply the sounds of the notes when played quickly in succession. this book gives me a new perspective on his use of 'the golden mean' much like mozart. u can find in mozart exact golden mean proportions. it is quite interesting to hear this about debussy.
do you think poissons d'or (images ii) or l'isle joyeuse is more awkward?
