The point of sound can be felt on an
acoustic piano. Electronic pianos and organs have them but they are
pretty much indiscernible.
Slowly press down on an acoustic piano
key without making it sound. At one point you will feel a little
bump. If you press beyond that bump, the key will give way and you
will be pressing into the keybed. If a pianist wishes to achieve
that pearly sound of fast and light notes, they need to learn to play
to the point of sound.
As previously mentioned, pressing into
the keybed will force a stretch to the long flexor tendon which
creates strain. Not to mention, if you are pressing down into the
keybed, you can't move your hand or fingers up to the next note
because before you can play down you must first play up. Every
motion has an equal and opposite motion. This is where some pianists
and typists run into trouble because they are trying to maintain a
“still and quiet” or relaxed hand. It is in their relaxation
they are creating tension because when they use the wrong muscles,
they create tension, then they try to relax the very muscles they are
using.
When you kick a ball, you first back
kick. Swing a bat and you will first back swing. Cast a fishing
pole, back cast. Walk forward, press backward. Punch someone, back
swing. When you walk forward, as your left leg reaches forward your
right hip rotates backward. As your right hip rotates backward, your
right shoulder rotates forward. Every motion has equal and opposite
motions and your body is designed to work with other parts for
balance, relaxation, power and efficiency. When you isolate a part,
you will create problems. Pianists and typists are rarely taught
this. They think playing comes from the fingers but it shouldn't.
It should first originate from the larger muscles of the arm. When
the arm does most of the work, it frees the fingers to do some of the
more fine tuned movements and, to truly relax. BTW, the fingers
don't have muscles. They are moved by the muscles in the forearm.
When a pianist or typist tries to originate movement from the
fingers, they will strain the tendons.
In order to type or play down on a
piano, you must have an up movement to harness the power of gravity.
If you play with your fingers pressing down on the keys, you will not
have the power, speed and accuracy of the arms. You have probably
seen pianists playing with graceful movements. They are not just
putting on a show, they are feeling and moderating the weight of
their arm. Ideally, most of the up motion should be minimized once
it is in the brain. Even playing a simple scale, the arm might
change directions via the pronator and supinator muscles up to six
times. This is invisible to the eye but must be there in the player's
arm. If not, they will static load and create tension, cramps and
fatigue.
This law of physics also pertains to
other muscles such as your pronator and supinator muscles. If you
are rotating your arm to play a downward scale, your must first
counter rotate to give the arm both power and to control its
direction. Keeping all five fingers together and moving in the same
direction will provide great facility. Even the fingers you are not
using must go in the same direction and play down at the same time.
Some piano teachers call this “tapping.” It is when we stretch
our fingers out and pull in opposite directions at the same time we
create cramps and fatigue.
Keep in mind that all movement, once
learned and ingrained into the muscle memory of your brain, it must
be minimized to being invisible. The opposite motions are all there,
they just can not be seen anymore, however, the pianist will feel
them and it will be a feeling of power and effortlessness because
they are not using the wrong muscles to play. Most of us are taught
to use the wrong muscles, or, we are not taught anything. It is a
dangerous teacher who simply says to practice more, relax or
prescribes silly exercises to build unnecessary strength and
endurance, both which everyone already has aplenty within their arms.
The reason teachers think a student requires strength and endurance
is because the incorrect muscles a student may be using are indeed
weak and fatigable. Strengthening them reinforces improper movement
and sets the stage for the mythical beast called “repetitive strain
injury.”
