I've always been partial to sliding pentatonic runs like this Am one


And also sliding around in thirds like this Em run


A run like that is dead easy to learn as it's just running through the chords, and they're both useful as you can drop them into a solo - "going up the neck from lydian to the phrygian then back to aeolian" doesn't really make sense and wouldn't have any practical application.

Mr Seagull, you seem to know your shit, can you help me understand what RobChappers means here....

I asked - Can I use pitch axis theory in my playing, or is it more to illustrate modes of the major scale?

He answered - I use it all the time mate, it is strong practical theory! For example take a nice long 3 octave scale and play some lydian with it... then hit a minor chord shift it forward a semitone and your are shredding phrygian.
Nothing of me is original. I am the combined effort of everybody I've ever known.
