Wanting to become a 'cute girl', Chika Homura begins by joining the Wind Instruments Club which is struggling to find new members. After reuniting with a childhood friend, she and the rest of the club find many mysteries ahead of them, including their instructor.
The music and sound tracks were nicely done, the OP and ED were among my favorites of the season and the BGM did well to convey mood and feeling.
Aside from Chika and Haruta the other characters don't receive much development aside few defining characteristics. Chika is mostly well done, she is exactly who she is introduced as: a loud and active girl trying to become a 'lady'. Her ignorance to music is to be expected of someone who previously had all of no knowledge on the subject (Allowing explanations to not just be given for the sake of being told). Haruta is Chika's inquisitive childhood friend who definitely is more than meets the eye, while seemingly perfect on the outside he has been hinted to have been through a lot since he and Chika have been apart (Holding much more interest than the series itself). However his intuition is miraculous at times which is somewhat bothersome, luckily the series doesn't rely heavily on mysteries for much else than character introduction. These two share a a flaw that the show could probably go without; the attraction to their instructor. It felt rather shoehorned into the plot and doesn't serve much of a purpose throughout the series than giving Chika and Haruta something to 'compete' over.
The series by no means rushes itself to compensate for only having 13 episodes (aside perhaps mysteries lasting about an episode). This brings its own pros and cons. While preventing itself from overwhelming the viewer with too many characters or details about those characters. However this slows the series down significantly causing it to be rather uneventful and consequently boring.
Overall 7/10
It's easy to forget that this is an adaptation to a beginning of a series. If you find that you enjoy this then you'll probably want to pick up the manga, but if you're looking for a quick show that gets straight to the point then you may want to look elsewhere.
