Classi9 is a fun, light-hearted read. By no means would I call it a masterpiece, but the writing and characters were better than I expected. When I saw that the characters were re-imagined versions of famous composers, I was anticipating a barely cohesive plotline that leaned heavily on those as a gimmick. But, after reading this, I can say that I would have enjoyed the story even if the author had omitted that shtick and allowed the characters to simply be random people that she created.

Story: Historical, music-themed gender bender. I would say that it was a good example of those story types, so if that is the kind of manga that interests you, you'll probably like this one. Is the story believable? Yeah that's a definite no. Is it well-written enough that I could suspend disbelief and enjoy it anyways? Sure.

Art: Attractive and consistent. I would say slightly better than average. There is a fair amount of chibi art, if that is something that bothers you. Clearly drawn for the female audience - lots of bishounen. That being said, it is not a overly-flowery, starry-eyed shoujo style

Characters: Likeable characters. For the most part, not a whole lot of character growth. Some characters were well-rounded, others were not.

Enjoyment: As silly and gimmicky as it was, I enjoyed this manga a lot. My knowledge of classical music is pretty minimal, and I did enjoy the historical tidbits that the mangaka included in between some of the chapters. I get the feeling that if you are more knowledgable about classical music and composers, you will probably get frustrated and distracted by the historical inaccuracies that I am sure exist within this story.
