More than just the piano!

This is interesting, YMMV, of course, but it makes good sense anyway.



Nowadays, Schubert's music sounds differently compared to 200 years ago. To find out why, the body language of pianists is now being analysed.

"Pianists' playing technique has changed considerably over the last 200 years," says Christina Kobb, PhD scholar at the Norwegian Academy of Music. For the last five years she has studied piano treatises of the early nineeenth century in order to reconstruct the physical approach to piano playing at that time and to determine whether the music of such great composers as Beethoven and Schubert would sound differently with the reconstructed playing technique.

One of the most comprehensive piano treatises of the Viennese era was written by Mozart's student Johann Nepomuk Hummel. Such treatises describe how young students should be taught to use their fingers arms and elbows. The elbows should be held close to the body, the hands in an askew position and only the outer joint of the fingers should move when touching the keys. Modern piano techniques typically heldelbows wide to produce a stronger and equal timbre.

"The old Viennese technique that I have reconstructed provides completely different opportunities for phrasing and another interpretational space for the music than the modern technique does," Kobb points out.

The big question is whether the audible difference between the old and new playing styles comes down to the different techniques alone.

Rolf Inge Godøy, professor at the Department of Musicology, University of Oslo in Norway, has therefore analysed all the movements that Kobb makes while she is playing.

"The fundamental idea is that the body movements create the music. We cannot separate one from the other. This is the basic idea of musical experience. However, we need better documentation in this area," says Godøy, who is one of the world's leading researchers in the field of analysing motion in music.

Photographing the movements

Godøy receives invaluable assistance from the Korean researcher Minho Song, who analyses Kobb's playing style as she plays a Schubert sonata with both modern and old techniques.

He attaches 46 small pieces of reflective material to her hands and finger joints, and records all body movements with the aid of nine infrared cameras. The distance between the cameras has been carefully calculated to ensure that he obtains continuous images of all fingers, even if the pianist occasionally should hide her thumb behind the other fingers.

"We reconstruct each reflective point in a three-dimensional format to obtain exact data on how the different parts of the body are moving. We can rotate the images to see the finger movements independently of the camera angles, and we produce separate graphs that show the speed, acceleration and placement of the fingers," Minho Song explains to the reseach magazine Apollon.

The graphs enable the researchers to understand how the pianist is continuously planning the next event.

"We wish to find details in the articulation. Each keystroke is shaped by what you have done and what you plan to do. This is an insufficiently understood element of music," Godøy says.

Micro-insight

Since the cameras shoot one hundred images per second, the playback speed of the film can be reduced to study the details.

"This is putting music-producing gestures under the microscope. We can now study the tiniest of movements and gain insight into small details that create significant nuances of interpretation in the musical performance."

Hopefully, the results from the Schubert study will be ready this spring.

"We can already observe clear differences in the two playing techniques," Godøy says.

His next plan is to measure how pianists use the muscles in their arms, hands and fingers, thus to understand where the energy in their playing originates.

Body movements are very important, but even more important is instrument construction.  I see that the musician in the picture is playing some kind of electronic keyboard; she really should be playing an 1820 Broadwood fortepiano!

Only the outer joints of the fingers?  Tell me he means the second joints, puh-leeeze . . . .

I have enough trouble moving only my fingers! But it's easy to see why those 18th-century musicians advocated no arm motion; fortepianos  were so fragile back then that a forearm smash would probably have broken every string!

Probably just a semantic difference, Karl. You know, first floor, second floor etc?    There's no doubt Hummel could play the hell out of the piano. I guess the question is, did he know anatomy?  

I'm no pianist so I don't have an opinion about this. I just found it interesting.

Somehow this reminds me of Gould scrunched up, sitting very low.

And ... the word distal was invented for a reason.

Even some later Beethoven was like that?  Someone must have played slightly differently away from what the textbooks said, anyone with talent will find their own individual style within the conventions of the day.  So it may be important not to make this too constrictive.

Also, though of course it's interesting to see what some playing may have been like back then, that doesn't mean that other styles are invalid.  I know the article may not be saying that but I just wanted to make that point.  It's more about opening up some styles of playing rather than constricting it.

Ouch, reminds me of my dentist visits ...
