Inside his head is the rhythm of a computer.
Taking charge of Mario’s music is Koji Kondo (27 years old). He began his studies on the electric organ when he was in kindergarten. He doesn’t begin composing for a game after the story and images have all been completed, but rather he joins in the same brainstorming meetings as everyone else and imagines the sound of the game from these sessions. However, once Kondo has begun full-scale composition and arrangement, he doesn’t consult anybody.
Even when no interesting characters or good game ideas appear, days and months still pass by quickly.
When he makes the computer produce the sound of a piano, he is always thinking of what kind of tone it will have in the final product.
