When we first start learning the guitar there is a theory that we have to develop muscular strength in our left hand to fret notes. Some people go through great efforts to develop strength; this may include strengthening exercises, gripping machines and squeezing tennis balls. I even knew this person who would play scales and exercises while he was reading the morning paper.
The question is how necessary is left hand strength to playing good guitar?
To fret notes cleanly we not only need strength, but also accuracy and flexibility. If we are not accurate with where we place our fingers then the note will not sound cleanly, no matter how much pressure we use. In fact most people when they first pick up the guitar use too much force.
It is therefore important for us to use just as much pressure as we need to fret a note – and no more.
(See left hand tutorial for this) When we learn something new we are tense. However tension inhibits muscle movement. To move hands flexibly, cleanly and accurately on the guitar requires relaxation - the muscles must be soft.
If you are continuously practicing strengthening exercises there is a danger of developing muscle overuse syndrome or repetitive strain injury - RSI. If you ever you feel pain in your wrist arms or fingers, STOP!
The idea is to release as much tension as possible – this is how we really begin to learn. Become aware of tension in different parts of your body and try to release. The fingers are attached to the body which is attached to the brain. Relax the brain – relax the body - relax the fingers.
