The lowest note on a guitar is nowhere near the lowest note on your piano or keyboard. When a guitarist starts rocking with his standard E chord, he has just started off on the lowest chord/note possible and all subsequent chords\notes are gonna be *higher* than this. But If he starts the same tune in D Major for example, he can (almost has to) use chords & notes lower than Root chord which means he can get a different characteristic using the same intervals. Keyboards usually have more octaves, so you can just drop down past your root note whenever you want to. I dunno what the story is with violins & other stringed instruments.. prolly same as the guitar.
Im confused. Im no expert. I must look into different tunings.
All i would ever say about the characteristics of Major and Minor Scales are that they are Happy & Melancholy respectively.Everything else (which this person describes) is in the skill of the musician. IMHO. Major Modes are a completly different story.
Pls Correct me if im wrong.
