Here’s a link to a new lesson I have written over at tempomusicards.com on a couple new finger exercises you can try out. A video that will demonstrate the exercises will be up shortly along with this lesson.
If you have tried the finger exercise in the lesson on this site, this new lesson will give you a couple exercises that can significantly increase your fingers’ ability to stretch out for those tricky chords.
I have been using these two exercises (especially Exercise Two) in my daily practice lately and seen quite an improvement in my ability to stretch out for wide jumps and awkward chords. Keep in mind not to over-stretch your hand when using the exercises. If you feel any pain at any time, take a break and come back to the exercises another time.
Access the lesson here.
Good luck and let me know how you go with the exercises!
