Charge/discharge control circuit and battery device provided with same

Provided are a program and a sound output device for maintaining the interest of the user. A sound output devicewhich outputs prescribed musical scales comprises: a level information acquisition unitthat acquires, as level information, a user's sense of pitch; a sound output unitthat outputs sound of which the pitch has been changed under prescribed conditions based on the acquired level information; a response information acquisition unitthat acquires, as response information, a response to the change in a musical scale input by the user on the basis of the output musical scale; a correctness determination unitthat determines the correctness of the acquired response information; and a level determination unitthat determines the level of the user's sense of pitch on the basis of the determination result.
