Playing With Fire #5

In Playing With Fire #4 I mentioned dropping the hand or finger into the key. This is called playing with gravity or arm weight. Some pianists may complain that certain pianos have a stiff action or, when they are cold, they have difficulty depressing keys. That is because they are trying to use the flexor muscles or the non-existent finger muscles to play. Your fingers have no muscles. They are moved by the muscles of the forearm.

When a pianist plays with gravity, the keys go down effortlessly because they are not using any muscle to depress the key, they are only using gravity or the weight of the arm. The only muscle engaged is the bicep which raises the hand from the fulcrum of the elbow, then controls the descent.

It is important to note that once your finger depresses a key, after you hit the "point of sound," you unweigh your arm so that you are not pressing down, leaving just enough weight to keep the key down. Another source of the apocryphal "repetitive strain injury" is pressing into keys because pressing stretches the long flexor tendons and stretching can create strain and micro tears. Since tendons do not have an active blood supply to promote healing, the body places scar tissue in the wound but, scar tissue does not stretch and results in larger tears the next time you stretch.

Warming up through stretching is also a myth. What happens when you overstretch your muscles, you tear muscle fibers and the body rushes blood to the site to begin repairing the damage of the stretch. Since blood is warm, it gives the illusion of warming up. A better way to warm up is to sit in a warm room. Also, you can't spot warm up since your blood is always circulating. When muscles and tendons are actually cold, they contract and resist stretching. Stretching cold tendons is always bad because they are contracted, resisting stretching and more apt to tear than stretch.

It is sort of like stretching warm taffy into gooey strands. Try that with frozen taffy and it will break. It is important for a pianist to never play with a cold body unless you have mastered ergonomic playing and the laws of physics.
