Our second warmup exercise for guitar: a “trill” exercise. In music, a trill is played by going back and forth between two notes, usually in rapid succession. In this exercise, we practice playing trills with every finger in the left hand. Ultimately, this exercise isn’t really about trills. It’s about hand and finger development.
It’s remarkable how much this single exercise does for your fretting hand. Add this to your practice routine and just watch the results!
