"Rhythm is the foundation of all music--not rhythm in its metronomic
sense, but in the broader sense of proportion. I lay the greatest stress
on the development of rhythmic sensibility in the student. Rhythm gives
life to every musical phrase." Mr. Letz had a Brahms' quartet open on
his music stand. Playing the following passage, he said:

"In order to give this phrase its proper rhythmic value, to express it
clearly, plastically, there must be a very slight separation between the
sixteenths and the eighth-note following them. This--the bow picked up a
trifle from the strings--throws the sixteenths into relief. As I have
already said, tone color is for the main part controlled by the bow. If
I draw the bow above the fingerboard instead of keeping it near the
bridge, I have a decided contrast in color. This color contrast may
always be established: playing near the bridge results in a clear and
sharp tone, playing near the fingerboard in a veiled and velvety one.
