Nitaro's mother passed before he was old enough to remember her, and after smallpox leaves him blind at a young age he finds a connection to her through music and her shamisen guitar. Happily, Nitaro finds out that he has an aptitude for the shamisen and his skills are soon recognized by a goze (a traveling female bard) who takes it upon herself to teach him the traditional style of play. However he quickly realizes how restrictive this style can be and, frustrated, he begins the long journey to find and perfect his own style of play.
The studious and uptight Chiaki is well-known as the top pianist of his school, and dreams of becoming a world-class conductor like his idol, Viera; but his fear of flying (which makes studying abroad impossible) combined with a recent break-up and dismissal from his piano instructor causes that future to seem both bleak and unlikely. After collapsing outside of his apartment, drunk, Chiaki inadvertently meets a young woman named Nodame who, while quite talented at the piano, is unclean, clumsy, and haphazard. Despite being almost polar opposites, the two begin to grow closer and work, together, to overcome the obstacles in their careers.
Both of these series deal with classical music, Nodame Cantabile with the European style and Nitaboh with the traditional Japanese style. They are about accomplishing your dreams of music through hard work and dedication, and never deviating from the course that you have chosen no matter how difficult it is.
