What music was Kaori "playing" in the roof of the hospital in episode 21?


In the scene on the roof of the hospital, in episode 21, Kaori starts
mimicking playing a violin (around minute 10):

I tried to find out what music she was playing, but [ANN's page on the
anime](http://www.animenewsnetwork.com/encyclopedia/anime.php?id=16108) does
not list the music (at least yet).

**What music is this, and who is its author?**




It is "Saint-Saëns, Camille Introduction + Rondo Capriccioso". It was also
used in Episode 4, when Kousei and Kaori perform together for the first time.

I believe the segment we hear here begins around the time that Kaori starts
playing the violin again after stopping for Kousei. If you remember, she
encouraged him to start again. We hear a lot of Kaori's and Kousei's thoughts
during this time, where she wants to join him in the journey to being a
musician. To struggle together no matter how dark the road ahead is. She is
most likely trying to bring back Kousei's memory of the struggle they faced
together on that stage, and encourage him again to continue.
