N is for Nocturne
Nocturne: a piece appropriate to the night or evening, an instrumental composition of a dreamy or pensive character.

Old, romantically dreamy nocturnes were something that held a special emotion for Ayako. They left the sense of growing older and becoming an adult. They reminded her of the evening parties that her parents would hold mostly in the winter months – she used to not be able to attend them until she had become older.
And by then, she had become the guests' favorite part of the evening parties. Everyone would become so quiet and attentive when the teenage Ayako would sit down and play a nocturne on the baby grand piano for them. The piece was always her choice.
