In the world of classical music, Chiaki Shinichi is a stellar talent in the making; yet with everything going for him, he is nevertheless tied down by his own phobias. Unable to leave Japan because of his fears of flying and sailing, he finds himself in the company of another naturally-talented person, the very weird girl Noda "Nodame" Megumi. Together, the two find themselves in a slowly more intimate relationship, as they struggle to develop their talents and overcome their shortcomings.
Lonely Kaoru Nishimi has lost count of how many times he has moved schools thanks to his father's naval career. Newly landed in Kyushu, he finds most of his classmates instantly antagonistic towards him and suspicious of his elite background. Only two other students seem not to mind who he is – the infamously abrasive Sentarou and the gentle Ritsuko. Unbeknownst to Kaoru they have a passion for jazz, and they're about to pull him out of his stiff, joyless world into theirs of loose, swinging self-expression. Through friendship and frustration, love and despair, Kaoru will learn that life has a wealth of experiences in store for him!
Another josei drama/romance about music and musicians, though you can enjoy both without prior knowledge of jazz or classical music. Both have very likeable casts, and a similar art style and flow.
I would definitely recommend that you keep your music player handy (or at least youtube), so you can listen to all the songs mentioned- it makes both way more enjoyable.
Both Nodame Cantabile and Sakamichi no Apollon are based around people discovering and refining their own musical prowess. As another user said, both of these stories work a treat if you play the tracks mentioned whilst reading. Although Sakamichi no Apollon is more of a drama whereas Nodame Cantabile is more of a comedy, both are also similar in that they are heavily character-focused.
Both are light and heartwarming titles, where the main heroine is a very weird girl. Whether you call her a freak, or call her pure, the fact that her way of thinking is often hard to understand remains.
Both stories focus on a person (or group of people ) playing some instruments, and gradually getting better at it. Both titles include some musical trivia
Hino Kahoko is a sophomore at a high school which caters to both general students, and the musically elite. On the first day of class, Hino meets a fairy named Lili and is entrusted with a magical violin; this violin has the ability to express the music in someone’s heart, even if they do not possess the talent for playing the instrument. With the violin in her care, Hino must now compete in a musical competition, but the guilt of not having true musical talent consumes her. Lili’s dream is to bring happiness to people with music, but Hino isn’t sure she has what it takes to be the one to do it. Can Hino perservere, or will she abandon Lili’s dream?
If you like classical music, then La Corda d'Oro is another anime that you might want to watch, along with Nodame Cantabile. It's reverse harem and the main character plays the Violin. The guys are cute and there's lots of romantic moments between the main character and the bishounens!
If you liked L-DK or Nodame Cantabile, you may like the other one. Both series evolve around the love story of schoolmates living next to eachother. Nodame has more comedy and slice of life part in it. L-DK is smoother and maybe more dramatic than Nodame. But both series have romantic couples going to the same school and living next to eachother.
If you liked Nodame Cantabile or Piano no Mori, you'd like the other because both are stories in which music (the piano) takes a central place, with sprinkles of comedy here and there.
The main characters are similar as well: Kai and Nodame both have extraordinary talent for the piano, but both of them play in a way that isn't exactly 'suitable' for competition. And then we have Amamiya and Chiaki, perfectionists which were both raised playing the piano by-the-book.
The main difference between these two stories is that Piano no Mori lacks the romantic element present in Nodame Cantabile, and the latter leans more towards comedy.
