This is Madness

 

I recently saw an article in the magazine Piano Street regarding a new device, basically a robotic hand, which, when attached to the hand, is touted as being able to increase the speed at which the pianist plays. 

Here is the link:

When Practice Stagnates: Robotic Training for Pianists

As you see, the device fits on the hand and the makes the fingers move rapidly. The hand isn't really doing the work, it is just passive. The article shows a pianist before and after using the device, and demonstrates that there is an increase in speed even after the device is removed.

Wow, there is so much that is wrong about this.

First, the device only deals with the fingers. As you've read in this blog, I don't subscribe to the common misconception that piano technique is all about the fingers. It is more about the integration of the arm, hand and fingers (and even the torso). The example shown in the video is a pianist playing "double thirds" (a slow trill on two notes) which essentially stays in one place. This, however, is not real life. All challenging music for the piano will require you to movie up and down the keyboard. Chopin's "double thirds" etude (Opus 25 #6) starts this way but then proceeds to move up and down the piano in scales and other patterns in thirds, which obviously must include the arm. ("The hand isn't going anywhere the arm doesn't take it.")

Second, the article admits that, even though the hand is passive, there is still the possibility of injury with the device. You don't say! Over-use of the small muscles is the main cause of injury and strain for pianists. The author of the original article states: "I'm a pianist, but I injured my hand because of overpracticing. I was suffering from this dilemma, between overpracticing and the prevention of injury, so then I thought, I have to think about some way to improve my skills without practicing." Instead of questioning his whole approach to technique he just looked for a workaround, a way for something else to do the work for him. Learning to use the larger muscles of the arm and less reliance on the fingers would have prevented his injury. The late pianist Leon Fleisher developed dystonia in his hands and had to stop playing altogether. After many attempts to cure it (which didn't work), he discovered he could play if he stuck to pieces that weren't so "finger-y," that is, pieces with big chords, for example, which used more of the arm. As it turns out, dystonia is a "scrambling" in the brain from over-use of the fingers, and not a physical problem with the hand at all. To me, that indicates you could have the same problem even if the robot is causing the movements. It's still affecting the brain.

Third, the playing in the article's video sounds.... well... robotic. Of course it does! The device would not allow for any nuance in the playing. If you've been reading this blog, you know I really reject the idea of practicing without musicality and then hoping you can flick a switch and play musically when you want to. Listen to a great pianist play the Chopin Double Thirds Etude and you'll hear there is a lot of nuance, and can, and should, be played very musically. To play musically, you have to practice playing musically.

One valuable thing that this experiment with the robotic device demonstrates is the power of the brain in everything related to piano technique. The article states: Surprisingly, the untrained hand also showed improved performancee, demonstrating an inter-manual transfer effect. So, in other words, it was something that happened in the brain which caused the other hand -- the one not trained with the device -- to improve as well. Wouldn't it be better to explore how to change our brains everytime we practice, rather than use a cumbersome device with potential for harm? I emphasize this in my teaching. See my posts "It's All (Neuro)logical" of December 2020, and "Practicing to Build Your Brain Power" of August 2020.

I doubt whether this device will come into common usage due to cost and other factors. But if it does, I shudder at the thought of every beginning or intermediate, or even advanced student starting to practice using this device. It is frustrating when you feel you reach a "plateau" in your piano practice and you aren't improving. Some of this is the natural learning curve. But most of it is probably how you're practicing. Some of the things pianists do to try to break through a plateau are useless and some are just plain harmful. In an upcoming post I will discuss what to do about plateaus.
