The comparison between the theremin techniques of Lydia Kavina and Clara Rockmore is quite interesting but the authors fail to address what is perhaps the most important aspect of their subject, and that is the impact of the particular technique on musical expression.
It's as if they were describing, in minute detail, the characteristics of two completely different paint brushes with no mention of how the differences affect the practical application of paint to the canvas. Also, there seems to be an assumption on the part of the writers that Lydia and Clara are playing at the same level of virtuosity. They are not, but I doubt the authors have the musical competence to recognize why. They have carefully WATCHED Lydia and Clara play, but they have not LISTENED and I suspect they do not have the ears to do so.
It might interest the writers to know that there is far more tension in Lydia's "lightness" than there is in Clara's "bound flow" and this has caused Lydia plenty of problems in her theremin playing career.
While I do not doubt that the theories involved with LMA can be flawlessly applied to some activities, the failure of the authors to understand the theremin has compromised their conclusions in this particular instance. They have, among other things, mixed their apples and oranges by comparing the physical demands of an aleatoric piece like THE SWAMP (Lydia Kavina) with Clara's precision performance of HEBREW MELODY.
There is an interesting discussion of "recuperation" - the ability of an instrumentalist to recover from the tension of the execution of a musical phrase. One of the things that can help enormously with this when it comes to theremin playing is the use of an audio pitch preview (something I have been promoting for years).
There are so many holes in the above instrument design thesis that it strongly resembles a heterodyne Swiss cheese. Over the years, I have read many seriously flawed papers of this sort on theremin design and technique, all of them written by people with impressive credentials but who do not play.
