lately i've noticed that when practicing forms and making up lines/goofing around in a minor key, all i have to do is play the root note, then every other note i play is just in the relative major scale. it's as if i could just play the root, then slide up 3 half steps and play major. so is there any real difference/point between playing minor or root and relative major? thanks.
edit: this is not when playing classical or jazz or funk, more indie-esque... if that makes a difference.
Check out a theory book on modes. Good stuff to be acquainted with.
The same diatonic collection of notes can be played so as to imply seven different scales.
And that's a really good thing to 'shed. Gets you away from finger patterns, and more in touch with the fingerboard.
