If you are a musician, apply this form of cognitive enhancement to your playing.If you are a bass player and tend to play the higher tones with your left hand, try switching hands. Or if you’ve never learned to tap, give that a try.It’s also fun to try playing left-handed if you normally play right-handed. Be sure to put in 10 to 15 minutes of consistent, daily practice.If you play piano, cross your body by playing the bass notes with your right hand and the higher notes with your left. This will not only improve your musical intelligence, but provides incredible brain training.
