My idea is that the water vibrates and sends sound waves through out the water and up the bottle creating the echo. I think that the more water the more high pitched the sound because since in water there are less particles to interfere with sound waves and water muffles sound. So in the bottles with less water the sound is deeper and lower pitched because the sound waves are mostly reverberating against the bottle.
because it fell in a forest
The amount of water put in determines what the pitch/tone is. See, sound is made by vibrations. The amount of water put in adds dampening to the vibrations, making it deeper.The xylophone is a percussion instrument and it works when you tap it and when you hear a soud it's starting to get low and higher sounds.=)
they make different sounds and the xylophone is bigger the glockenspiel has metal bars while the xylophone has wooden bars
Don't hit it as hard, or use a softer mallet.

The word "xylophone" comes from the Greek meaning "wooden sounds."
Don't hit it as hard, or use a softer mallet.
No you make the sounds by tapping on different keys, so it is a percussion instrument.
