This is a question I see/hear asked a lot. Much like confusion over modes (it’s pretty much the same question), the reason people have this question is because they’re focusing on the wrong thing! If you’re just looking at the notes, then there isn’t any obvious difference. However, if you focus on the intervals and how all the notes relate to the tonic, then the differences are really clear.
But what’s even more clear is the sounds! So give the video up there a watch and see if you can’t hear the difference.
