It centered on the life of four members of a boy band, each named or nicknamed after a famous classical music composer, as they lived a modern adventure in each episode more or less equivalent of the moment in the real composer's life that motivated him to write one of his works.[2]
Beethoven, the fattest boy of the lot who always has a drumstick either behind his ear (held like a pencil) or sticking out of his pocket. He has long black hair. The character is named after Ludwig van Beethoven.
Chopin, the keyboard player for the band, can be recognized by a strand of his brown hair that would always get into his face, but never bothered him. The character is named after Frédéric Chopin.
Verdi, of Italian descent who lived with his family above a restaurant they own. The restaurant is called "La Traviata" after the opera of the same name. His hair appears to be black shaped into points that stick out using styling gel. The character is named after Giuseppe Verdi.
The band had a small dog named Pimples (Mozart's dog) and three girls who admired them. Their old-aged music teacher, Professor Solfa also made prominent appearances.
Blackie, the antagonist, was the son of the president of Col Records (Col being the Spanish for Cabbage, and thereby the logo of the company). His hair style resembled an eighth note on its side.
