Interesting story. Well done. 

Uh oh. Son versus dad. This is tense!

Fuck me Amadeus. Totally made me think of the old Falco song, rock me Amadeus and now it is stuck in my head. lol. 

lovely!

oh my.....

Very intriguing and looking forward to more. Thank you!

All's well, that end's well, and everyone is in tune.

Can't wait to see ,what happens next.

Well, who will she end up loving, father or son, either way someone could have their heart broken.

Underneath the apparent fickleness, she was looking for her soul mate.

As a musical ending (all in good humor):

Through her open door, Hermione could hear the Sibelius violin cadenza, and she thinks, "Fire without warmth.  My Anthony is back."

Later, she learns that Amadeus is performing Tchaikovsky, and she thinks, "I do have a place in his heart."

(Was this too interactive for a review?)

Good build up although it leaves Anthony as a mysterious character which might have been the intent.  Explosive, cliff-hangar ending.

A well-constructed chapter (although I feel slow since it took awhile to recognize the title and structure as a Bach composition), and I've always thought that Hermione was better paired with someone creative or artistic.  The prose flows even though it is wordier than my usual preference.
