Thank you for the explanation. So are these octaves simply differentiated by their hertz measurement? I guess what I'm struggling with is that we are supposed to count out the intervals when playing on one string, but I'm not seeing how that equates when we move two strings over and then down several frets to find the direct octave. It seems like we're just directed to do that, but I don't understand why quite yet. So would the C on the high E string vibrate twice as fast as the C on the low e string?
