This is something intriguing you touched upon. Do you happen to know, if she was able to deal with the more monotonous types of 'music', like African drums, or dance styles like minimal techno? I also wonder if other types of sounds, like a single tone, birds signing, or even human voices, was something difficult for her to grasp. Wondering as well how she was able to retrain herself again and if the quality of her music is at least the same, better, or worse compared to before the illness and surgery? Maybe I shall read the linked articles at the end of your post :)

Great read!
