Lesson #1: This lesson is to upgrade your bodily response to the rhythm. You tap on your lap with your hand alternatively. As you speed up the tempo, your non-dominant hand tries to move with your dominant hand. Thereby misses the beat. It becomes apparent as you set the tempo faster.
Lesson #2: This lesson is to separate the movement of your ring finger and little finger. The trick is that you practice this lesson along with "Take Five"
Lesson #3: This lesson let you memorize the spacing of each key if you try using keyboard. It can be nice alternative to Hanon tutorials. And you can use "Unsquare dance" of Dave Brubeck for the BGM.
Lesson #4: You will let your fingers move smoothly so that each finger of non-dominant hand can hit precisely where required. You practice this routine with usual 4 beat tune as the BGM.
Lesson #5: This lesson strengthen your finger muscle. Don't overdo this practice. It may hurt your finger muscle. 16 bars every 12 hours would be enough. And you'll know it takes time to get enough reflex to your non-dominant fingers.
