One of my favourite Chopin etudes is Opus 10, No. 12 (Revolutionary). See below. One website describes it this way:
"The Revolutionary Etude holds its place as one of the most eminent and well recognized of all of Chopin’s compositions. Beginning with the first dramatic chord all the way to the impassioned conclusion, this piece is an outpouring of emotion."
Chopin is just another example of the richness that people with disabilities can bring to the world.
