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.
What else can I help you with?
