Rubberband power for better classical guitar tremolo technique

Anyone familiar with pinkus erectus? It’s a latin term for stiff pinky. Pinkus erectus is something guitarists don’t want in either hand, but I’m going to focus on the playing hand here. Pinkus erectus is probably caused by tension in the hand, arm and shoulder. The playing hand’s pinky becomes rigidly stiff and straight while playing. How is this harmful to classical guitar technique? When your playing hand pinky becomes stiff, your “a” finger suffers - feeling weak, uncoordinated, and not under control. These two fingers need to work together instead of fighting each other.

I was trying to think of someway to market a rubberband to classical guitarists without anyone knowing that it was a rubberband. The rubberband is a good tool for correcting this flaw in classical guitar technique. Take a rubberband or some tape and loosely (not too tight) wrap it around the ring and pinky fingers between the tip joints and middle joints of the two fingers. If you haven’t been playing long or have never worked on your technique, you may want to start out playing scales with the m and a fingers or perhaps just open strings. Watch the ring and pinky fingers and concentrate on making them move together. Whatever the ring finger does, the pinky should be its shadow.

I like to do this while practicing the tremolo. Wrap those suckers up and make them move together. Heck, I even work on Recuerdos de la Alhambra this way. Give it a shot, it will really help your classical guitar playing hand technique.
