Reddit mentions of Heavy Metal Guitar Method - Modes (Instruction Series)

Here's a quick explanation. Many people change keys using the circle of fifths/fourths. You can also change parallel modes using the circle of fifths/fourths. The guitar is tuned to the circle of fifths/fourths (except the B string), therefore it's very easy to change modes by moving a pattern down/up a string (accommodating the B string of course). Maybe I should make a lesson where all the strings are tuned to the circle of fifths? It might make people understand.

Parallel modes are basically when you change keys but emphasis the same note. For example, you're playing in the key of C. Change to the key of Bb (via circle of fourths if you want). And emphasize the C note. Since C is the 2nd note of Bb you are playing C Dorian. i.e. C major to C Dorian

There is another type of mode called "Relative." It's when you stay in the same key. The key of C is C D E F G A B. If you played those notes and emphasized the D you would be playing D Dorian. i.e. C major to D Dorian

I think if you study Chart 1 it should become clear. BUY A NOTEBOOK. Think of it as a puzzle. I've got 30 or more notebooks filled with this stuff. ( http://i.imgur.com/gpdp5.png ) It didn't come to me overnight.

Here's a great mode book: http://astore.amazon.com/themachiguita-20/detail/0895246627
