To preface this review, I am a (hopefully somewhat) seasoned classical musician, so I have a fair amount of knowledge going into the manga. This is a reverse harem (guys fight over a "girl") AND gender bender manga (girl pretends to be a guy), so if you're not into that stuff, go read something else.

Story: 5. There were definite plot holes that the author put in the plot. Each of the composers is from a completely different era; at least the author could have ordered their age a bit better? For example, Haydn is portrayed as a little kid, but Mozart, who is drawn much older than Haydn, definitely looked up to Haydn as a budding composer and musician. Just saying. Mozart is god, but not god to the point where everything revolves around him. Other than that, it's a decent and lighthearted plot but really not anything special.

Art: 7. It was clean and well drawn for the most part. However, the mangaka obviously does not know how to draw certain musical instruments which put me off a bit (if you want to see a good example of musical instruments in anime, watch Hibike Euphonium. Gosh they did an amazing job animating that oboe).

Characters: 6. The author basically went on the classical composer stereotype and ended it there. Also, the MC is a guy IRL but is a girl in the manga for some odd reason which I feel doesn't do the real composer justice. However, I'm somewhat biased towards this whole situation, but the characters aren't too deep or unique so it gets a 6 either way.

Enjoyment: 8. Guys, there's finally a manga about classical music that's not Your Lie in April! I enjoyed reading this manga and relating it to my personal knowledge of classical music.

Overall: 6.5 Mediocre plot and characters, but it's not easy putting together the pieces especially with composers ranging from the late 1600's to the mid 1800's. I'm a classical music buff, so combining two things that I enjoy really just made this series so much more enjoyable. This series is definitely a good stepping stone for those who want to know more about classical music and for those who want something in the same music genre as Your Lie in April.
