These are known as "modes" or sometimes "church modes" and they are different ways to play the same notes. Wikipedia has a page
here.
There's an explanation/demonstration I like, in English/American,
here, but you may be able to find a version in your own language.
Thanks Gordon, Great video, I know this guy well. And yes you are right, fundamentally "different ways to play the same notes". My point is All scales are variation of the Major Scale. The Ionian (Major) scale is based on intervals of W,W,H,W,W,W,H while the other modes are every other combination of intervals. That consideration is addressed in my Music Theory 102.

Or maybe I need to change things up as Mario suggested.
