Hi all. I've been trying for the past couple of weeks to learn more about musical theory: scales, modes when I ran into the word 'tonality'. It was someone saying that 'difference between various modes in a given scale is tonality'. I'd like to know why are modes different from each other as long as we just start the scale from another note and swich chords according to that. Also please explain the word 'tonality' to me. Thanks :-)
