composers give the viola special attention is because France now is
ahead of the other nations in virtuose viola playing. It is practically
the only country which may be said to have a 'school' of viola playing.
In the Smetana quartet the viola plays a most important part, and
Dvořák, who himself played viola, emphasized the instrument in his
quartets.

"Mozart showed what the 'cello was able to do in the quartets he
dedicated to the ''cellist king,' Frederick William of Prussia. And
then, the 'cello has always the musical importance which attaches to it
as the lower of the two 'outer voices' of the quartet _ensemble_. Like
the second violin and viola, it has experienced a technical and musical
development beyond anything Haydn or Mozart would have dared to write.


REHEARSING

"Realization of the Art aims of the modern quartet calls for endless
rehearsal. Few people realize the hard work and concentrated effort
entailed. And there are always new problems to solve. After preparing a
new score in advance, we meet and establish its general idea, its broad
outlines in actual playing. And then, gradually, we fill in the details.
Ordinarily we rehearse three hours a day, less during the concert
season, of course; but always enough to keep absolutely in trim. And we
vary our practice programs in order to keep mentally fresh as well as
technically fit.
