1- dont look at your hands try to weed yourself from reading music sheets and improvise more often

2- treat both hands like two different people playing

3-Play RH sounds JUST LIKE A REAL MUSICIAN PLYING THAT INSTRUMENT WOULD PLAY IT NOT LIKE A KEYBOAD PIANO PLAYER

4-dont look at your hands try to play with a blindfold as an excericse!

5- practice practice practice as much as possible

6- go watch and absorb other people playing arranger kbs in your area

7-ask question on forums

8-practice your TIMING BIG TIME use a metronome if needed specially in betwen variations, fills, & sound changes

9-"LOVE" PLAYING EVERYDAY music is an expression of your inner soul!!!
