It is not necessary that the anime of the musical genre be filled only with songs, dances, music. Most often, this genre is presented to the viewer in conjunction with other areas: romance, slice of life, and even drama. For example, in the center of the plot may be the main character, endowed with musical abilities. But his path to fame will be difficult and ambiguous, as happens in real life.
Musical instruments, bands, vocals, dance floors, shows, competitions, a world tour or an underground circle – all this can be reflected in the anime storyline. But the main character is still a person.
