What is the fine-grained topic of the following text: this is a really hard song for me to sing... when I first decided to remake this I tried to sing normally for the verses then an octave higher in the choruses (because the chorus was originally too low) but then that didn't work (chorus didn't sound good because I was singing so high) so then I decided to raise the pitch of the whole song to what it is now so that I can sing the whole thing at the same level. Only return the topic.
