click the left key and you can change the pitch higher and if you click the right key you change the pitch lower. And if you want to change the volume click the up key and you turn it hight but if you click the down key you change it lower.
enjoy the music if you want or you can get the sounds by clicking see inside it's your choice. Also my favorite one is I use to hear a sypmphony and l'étoile d'afrique. :)
