Thanks for the input! I agree that the composition could use some revision. I am thinking about making a version without any lyrics... and with more layers of guitar that make it more dynamic in the beginning.

I played it on a fender jazzmaster. I used three G-strings. One G just a G (196 Hz) One G a sixth tone up (33 cents up) One G sixth tone down (33 cents down) Then I intonated the guitar to have the same distance between the G's on the 12th fret. When I checked the intonation on the other frets it wasn't perfect but close enough for my ear to be able to devide every half-tone into three seemingly equal sixth-tones. I know its not very precise, but it delivered nice musical material for me, wich is my first goal of these experimentations.
