In piano playing, what does “to caress the keys” mean?


There is an old technique called carrezando which literally means to caress the keys. Carrezando playing can injure a musician, it is very dangerous. The reason is because people think it is a technique when in reality it is the symptom or end result of technique. It should not be sought after but rejoiced when it appears.

This is a condition of virtuoso teaching. Many virtuosos move properly and never fully learned the biomechanics of playing because playing well came naturally to them so when they teach, they tell the student what they feel and not what they are doing to get that feeling. The student then tries to force that feeling into their playing but they can make many mistakes while trying to obtain it. Virtuosos are often the worse teachers because they sometimes don’t know how they do what they do.

Consequently students who try to force caressing into their technique begin pressing into the keys, playing with flat fingers and doing all sorts of things which will strain the tendons and then crippling pain will ensue over time because the damage is cumulative. The pianist will ignore the warning signs until one day something just breaks.

Ergonomic playing requires in/out motions, up/down, forward/backward and left/right. When you combine all these movements the player begins to play up and allows gravity to play down. The symptom of the congealment of all these motions is the feeling of caressing the keys. The pianist should not be caressing them but should feel like they are caressing them. When done properly the pianist won’t even feel their fingers because the skeleton will be playing from the arm muscles while the tendons in the hands predominately relax.

Much like petting a dog. Your arm lifts up, you move it toward the head, then down, then you pet down the dog’s back. There are four movements there and without them, there would be no petting. The petting is the result of the four movements where the hand appears do be doing the petting, using the arm.
Better yet, lay your arm on a table and lift your elbow off the table, allow your wrist to flex but keep all your fingertips on the table top. Now pull your arm off the table. Feel that your fingers are caressing the table but the fingers are NOT doing the caressing, it is the result of the arm pulling away. THAT is the carrezando technique. 

But every motion MUST have an equal and opposite motion. Like petting that dog, before you can pet down the dog’s back you must first lift up and forward before you can drop down and backward. If you focus on caressing, you will lose the equal and opposite motions required to play properly. Your fingers have no muscles, all the muscles which move your fingers are in your arm. The finger bones move by a pulley system of tendons. All these equal and opposite motions are what gives a pianist a graceful look but some players force that look into their playing. Now, some schools of technique, such as the Russian, will teach you to do this hoping that carrezando will magically appear but shortcuts often come at a cost. If not pain, ignorance of the mechanics. 

It is erroneously thought that the carrezando technique will give you great speed and a very light pearly touch. Again, that is the end result feeling of a proper technique. Don’t ever seek it, it will find you if your technique is proper.

First, you have to find a good teacher. If you want to find a good teacher, don’t listen to them play, listen to their students. If 90% of them play the way you want to play, you found the right teacher. Hopefully that teacher provides student recital opportunities for you to go hear several at a time. Otherwise, go to any of those ubiquitous Chopin competitions and ask the good students whom they take lessons from. CAREFUL the student isn’t a virtuoso whom the teacher is just guiding.

*I* have a virtuoso student but it is nothing I did. The kid just plays correctly naturally and i keep out of his way.

Do ergonomic keyboards and mice really help to prevent/decrease pain?

Pain and hand problems are caused by moving improperly. Ergonomic equipment, in theory, is designed to force your body into proper positions. They CAN work but it would be better for you to learn how to move ergonomically without the equipment.

The reason is, let’s say you have an improper ulnar deviation when you type (wrist twists to the left on your left and right on your right), you can still execute that improper motion with an ergonomic keyboard and, what good is fixing your typing deviation when you open doors, brush your teeth, write, use your phone or drive your car with the same deviation?

You can’t spot fix ergonomic problems. It is all or nothing. That is why people don’t heal because they try to fix isolated symptoms and not everything that is part of the problem.  You may have pain in your wrist but that is only the location of the symptom.  The problem is most likely how you are using your whole arm.

Often it is not a single movement that is a problem but a cavalcade of movement issues. You may type with flat fingers, curled fingers, too much pressure, equalized fingers, not enough “up,” radial deviation, you may abduct too much, you might isolate a finger, dorsiflexion, have an isolated elbow or shoulder . . . there are a lot of motions we should not do but we do them because many of us are lazy and unaware.

In the old days, manual typewriters forced us to type with the weight of the arm or, gravity.  Today's effortless keyboards have insidiously encouraged us not to use gravity and the fulcrum of the elbow to type and thus, we isolate smaller parts which strain our tendons. There is no such thing as "repetitive stress."  There is only improper movement and if you move improperly, all movement is then "repetitive stress."

Imagine casting a fishing pole with just your fingers, you'd probably hurt yourself.  Now imagine that only with the wrist.  That is better but still not optimal.  Now with your elbow.  Better.  Add the shoulder.  Notice how you are now using all the parts of the arm for one movement.  No single part is isolated but they all share in the casting, including but not exclusively the fingers.  Now as you cast, notice how your feet are planted, how your weight or center of gravity is distributed, your back and abs, notice also the equal and opposite motion required to cast.  In order to cast forward you must first cast backward.  Typing, too.  In order to type down you must first have an up motion.  Without it, you will strain your flexor tendons.  That is also the most dangerous part of using a mouse.  We rest our index finger and long flexor tendon flat on the button and click with no "up" or equal and opposite motion.  There is nothing wrong with the mouse, only how we use it.

The laws of physics must be obeyed. Break them and there is a price to pay.
