In this room, you get some glasses and water. Put different amount of water in the glasses and make them into different pitch. It's not a easy thing.

You will have a machine on the screen to help you find the pitch.

You know the glasses and water could create different height of pitch, but you never try this before. You start with the lowest pitch. It's really hard to get the exactly correct pitch although there's a machine help you. You tried 7 times to get the first pitch correct. For the following pitch, you take less time than the first glass. 15 minute later, you finish all the pitch, it's much more quick than you think. You use them to create a short simple song. But you feel pity of cannot hear the sound.
