Until Mr Android tells us which it is .... that's what I thought also, Christoph. But, if you look at it as the EBGDAE in that order, then it IS the notes of the C major scale. So, what MODE would you call it ? G mixolydian from high E "G" note down to open low E, or maybe it's E Phrygian from open low E to high E "G" note.
