Nuages (Clouds) from Trois Nocturnes pour orchestre

This is a try of transcription of "Nuages" (Clouds, or Cloudy skies in English ?), the first one of the three Nocturnes Debussy composed for orchestra in 1897-1899.
The composer wrote these words "Nuages : it's the sky's immutable aspect with the slow and melancholic procession of the clouds, ending in a grey-toned agony, sweetly tingled with white".

Nuages has been my very first exposition to Debussy's music as a listener, and the declic to have a try at the organ comes from a comment by Sandrine about some Froberger uploaded by Vannou : "That makes me thinking of a winter landscape covered with snow and above big grey clouds...".

Last : if you want to listen to Vierne's Arabesque finely played by Hoofdwerk, you may perhaps note that Vierne is sometimes rather close to Debussy.
