Please need help with a Bleach song that has violin and bells?

There is a song in bleach that plays During an ominous event is about to happen- not ominous premonition- confirmed to have played during episodes 210 and 293 when kensai is discovered by hirako to be a hollow and when hitsugaya is about to charge aizen with his bankai. Its instrumental only and has bells with the violin leading and the bells gonging. Specifically hitsugaya says 'if my blade is full of hatred then I'm also unworthy to be a captain', that's right, I'll gladly forfeit being a captain to kill you aizen take your stance! Please help!
