Has anyone here ever thought about how strange the concept of an octave is. I mean, how are there only 12 types of notes in the entire universe? How is one higher note the SAME as another lower note. Is anyone as fascinated by this as I am? Also, have you realized that every time you cut a string in half you go up an octave? don't believe me? scale length is not measured by the distance from the nut to the bridge. That measurement is irrelevant. Scale length is the distance from your nut to the 12th fret doubled. And the 12th fret is....YES an octave. Also, ever wonder why frets get closer together higher up the neck? because the 24th fret has to be 3/4 of the way up the scale because that is half of half, which goes up another octave! So you have to fit the next 12 frets in half the space that the first 12 frets were! I find this extremely cool and fascinating. There's probably some very simple scientific explanation for this, though. Do you guyz find this as cool as I do?
