Pianist/composer Sergei Rachmaninov was possessed of both unusually large hands and a staggering lack of empathy when it came to writing piano music for other people.  Hyung-ki Joo is by no means the first pianist to have been confounded by the mammoth chords of his Prelude in C sharp minor (Op.3, No.2).

He probably is the first to have come up with this particular solution helped by his partner in crime, violinist Alek­sey Igudes­man.
