Chopin Fantasie Impromptu sheet music

I remember that day when I heard Chopin's Fantaisie-Impromptu for the first time...
I was eleven years old. We had a music competition in our school. I took the part in that competition and had already performed my program. As far as I was free I came to the concert hall to hear how other participants were playing. When I came into the hall many other people came with me, although there were no free places already. So we had to stand on ours feet to listen a next performance. Next was the performance of a very talented boy, a pupil of our school. All listeners had been waiting his performance. He walked out on the stage to a thunderous ovation and began to play his program. The first piece was Fantaisie-Impromptu op. 66 in C-sharp minor of Frederic Chopin. The beginning of this piece is full of virtuosic passages and he played it really amazing. But that was not the place I was impressed by. When fast passages finished the middle part begun. When I heard the melody of middle part of Fantaisie-Impromptu I thought that I had never heard so beautiful music in the whole my life before...
