See that's what I was trying to say but in another way. See.. I don't know where every single note on the entire fretboard is.. I don't think I ever will to be honest. :o
So what I do is I go...
1. I need to play E Phrygian.
2. E Phrygian is based on the C Major scale.
3. Find C Major scale on guitar (in the 3 or 4 moveable shapes I know how to play it)
4. Start from (and end on) the 3rd degree/note of those C Major scale shapes.
Ideally I would like to know where each note is on the guitar. Ideally I would like to be able to work in terms of raised 4ths and lowered 7ths because that's how theory people tend to talk about scales.. but I am a very practical person, though also analytical and I get easily confused by all of that...
Conventional theory is great if you understand it.. but I tend not to understand it till I make it work for me.. then the methodology I used to understand it becomes my theory, not the original "correct" theory. :) I think it's great to be able to have 2 or 3 different ways of looking at the same thing because if someone is not getting it by one method, they can always look at the other method until understanding hits, then what the original person was saying starts to make sense too. :)
So if I grab my little thing again:
C D E F G A B C D E F G A B
1 2 3 4 5 6 7 8 9 10 11 12 13 14
Ionian
1 2 3 4 5 6 7 - Relative positions to C Major scale
C D E F G A B
1 2 3 4 5 6 7 - I added these lines but I don't really see how it helps
if you didn't already understand the theory stuff in the
first place.
Dorian
2 3 4 5 6 7 8 - Relative positions to C Major scale
D E F G A B C
1 2 3 4 5 6 7 - D Dorian scale
Phrygian
3 4 5 6 7 8 9 - Relative positions to C Major scale
E F G A B C D
1 2 3 4 5 6 7 - E Phrygian scale
You can see my methodology of finding the E Phrygian and ANY Phrygian mode, not the true theory of it...
