A little bit of musical history: Valse Triste (op. 44 no. 1) by Sibelius

I'm indebted to the Wikipedia entry for Jean Sibelius and the Afterword from Otto Taubmann's arrangement for piano duet (1 piano, 4 hands) published by Brietkopf & Härtel in Wiesbaden (Fall 1999) as "Edition 2273", as well as the William and Gayle Cook Music Library (which contains orchestral transcriptions for all his tone poems) for what follows.
