Hang on a sec, you mean, modes are basically emphasising other different notes in a scale other than the root note. for exam knockin on heavens door consists of the chords G D C, those notes of which are played and sustained alot in the solo. A different mode would be emphasising an E a lot would change it from G major to Mixo... scale, is that what you talking about by altering the root? [/B]

First, you're right about the emphasising thing. If you have a Cmaj, and you used the same notes but changed the root to the 6th which is A, that would be Amin (aeolian) scale. Then you'll find final note you'd like to end with is A. That's what I mean by changing the root.

Second , you miscounted the Gmaj scale :p. If you changed the root of a Gmaj into E, that would be an Emin (aeolian mode), not Mixo.
If you want to go Mixolydian from Gmaj, your new root would be "D".
