The second movement is based on a melody which is played 2 times at the beginning and one more time at the end. Let's say this movement is structured this way :

1- Introduction : 0 / 0'52"
2- Main theme : 0'52" / 2'57"
3- Variation A : 2'57" / 3'14"
4- Intro bis : 3'14" / 3'49"
5- Contrasting middle section : 3'49" / 6'51"
6- Variation B : 6'51" / 7'48"
7- Return of the main theme and final : 7'48" / 9'11"

Not sure to put the right words on each section...

Hope you'll enjoy this part.
