I dont even know how to describe it. I assume its some kind of synth. its in this video. https://www.youtube.com/watch?v=OXEOHHWH0CM[FONT=verdana, geneva, lucida, lucida grande, arial, helvetica, sans-serif] The sound really becomes noticeable around 35sec in. Not the water dripping or other percussion. the main synthy whistle sound thing. Please Help! thanks so much! [/FONT]
