The song is sei parte di me, by zero assoluto http://www.youtube.com/watch?v=9oc9qDKLtw4 The instrument is played at the very beginning, before any lyrics. I was thinking a sitar, but it sounds too throaty, I know nothing of guitars and perhaps its just a guitar tuned to sound like this. anyways I love the sound and I want to find more music featuring this "sound" and help is appreciated.
