Nothing, unless you want to learn to play the blues. To use the blues scales a student needs to listen to and enjoy blues music! Otherwise they have just learned some interesting sounds from an unknown language! Similar to learning a few words in a language you have never heard or will ever experience. A wasted exercise.
On the other hand let's explore some options on learning a new type of music.
- Head for YouTube and search "Blues Piano"
- Explore this list: In a bluemood: A personal listing of great blues pianists.
- Watch "The Blues" By Martin Scorsese. A great place to get an overview on the subject.
- Go to a blues club.
- Sightread some music from a blues piano book.
- Take some lessons.
Cheers,
