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!
In both animes, there is a strong love for the music they make and play. In La Corda there is a focus on classical music and Sakamichi focuses on jazz, but they both depict music the same way. They both have plenty of romance and drama in them too. If you liked one, you'd like the other.
