Yeah I kinda knew that if you were to move up to a different note you would be playing in a different key, but if you were to move up that Dorian pattern up to a different note, let's say a D note, and played any one of the seven positions of the major scale starting on that note, would it still count as a Dorian scale, rather it'd be D dorian instead of C Dorian?
Hope this clarifies what I'm trying to say.
So if you were playing in
C Dorian using the 'Dorian pattern - (
shape 2 of the Major Scale)' starting from the C note - and you wanted to still
play in the same C Dorian scale starting from the D note, then you would
use the next shape up in your Major Scale shapes (Shape 3 - or the Phrygian Pattern) - If you wanted to still be in C Dorian
starting from Eb then you would
use the Major Scale shape 4 (The Lydian Pattern) and
so on with every note in your scale - If you were just to move the Dorian shape up to D or Eb then you would be playing in D Dorian & Eb Dorian.
I think of it this way,
If I'm playing a 'Dorian shape' - it is silently connected to the 6 other Major Scale shapes surrounding it, so when I
move that same shape somewhere else, I'm moving the positions of the 6 other shapes connected, or more accurately,
I'm moving the whole key.
One crucial thing to note is that t
he scale will only really be considered Dorian if it's used over the right chord - For example if you played the
D Dorian shape over a C Major chord then your ear/your
listener's ear will always hear it as the C Major Scale starting from D - the Harmony underneath really dictates the Mode rather than the scale shape!
Hopefully that cleared it up a bit for for you! It's a bit wordy so I tried to bolden the important bits
So in a nutshell: If you move the same shape anywhere, you're moving the whole Key and all the relative shapes surrounding it. If you want to move position on the fretboard and be in the same scale/Key, you have to use the different shapes build off of each scale tone
