Director for Lectures
Smithsonian Institution
Washington, D.C.

Dear Sirs:

\J	I will be giving a series of seminars at the Peabody Conservatory in
 
Baltimore from November 18 to 20.  During this time I would like to offer your
 
institution a lecture on the early electronic musical instrument, the Rhythmicon,
 
which was developed by Henry Cowell and Leon Theremin fifty years ago.  Your
 
collection of musical instruments includes the only remaining Rhythmicon.
 
	I have done extensive research into the capabilities of the Rhythmicon
 
and have made a computer simulation of the instrument's performance.  My lecture
 
would include illustrations of Henry Cowell's notation for the Rhythmicon and
 
taped examples from Cowell's concerto, "Rhythmicana."  This work was composed in
 
part as a demonstration of Cowell's attempts to integrate rhythm and the ratios of
 
of the overtone series.  My talk would include some examples from Cowell's "Romantic 
 
Quartet" which set forth his acoustical theories at the early date of 1919.

	I think many people in the Washington area would find this talk to be of
 
interest and the Smithsonian seems to me to be the ideal place to present it.
 
I look forward to hearing from you on this matter.\.
