I use all-guitar-chords.com for all my chord and scale needs, but I noticed something, when I ... let's say want to write a solo in the key of E and I'll be using the Harmonic Minor scale, press "position: 12" and press OK, I get a E Harmonic Minor scale based around the 12th fret, but if I change the position to let's say 11, it's a completely different scale, moved down one fret but by no means the same scale only 1 fret down, my question is how the hell can I know what notes change when I move a position and / or is it possible to remember this formula easily. Thanks.
