About the Directors




Diane Sare, managing director

Diane Sare studied music education and trombone performance at New England Conservatory in Boston, before meeting associates of Lyndon LaRouche and the Schiller Institute in the 1980’s. The message of the Schiller Institute—for a true dialogue among civilizations, and a commitment to the right of every human being to progress—resonated with her New England Quaker upbringing, and she has been a collaborator of Mr. and Mrs. LaRouche since that time. In Washington, D.C. in the 1990’s, Diane directed the chorus in the Schiller Institute’s production of Through the Years, a play by Amelia Boynton Robinson, which had over 20 Spirituals in it.  Sylvia Olden Lee became Diane’s teacher and mentor on the performance of Spirituals during this time.

Diane is the founder of the Schiller Institute New York City Chorus, and its managing director.




John Sigerson, director

John Sigerson is a founding member of the Schiller Institute and currently its Music Director. He has worked for decades with Schiller Institute Chairman Helga Zepp-LaRouche and her husband Lyndon La-Rouche to bring about a Renaissance of Classical musical composition and performance. His musical education includes study with contrabass soloist Gary Karr, and voice with Mexico’s José Briano and Italy’s Antonella Banaudi. 

In 1992, he co-authored A Manual on the Rudiments of Tuning and Registration in which the general argument is presented why Classical music must be based on a fixed tuning of A=432 cycles per second. Sigerson has directed choruses for the Schiller Institute in Europe, Mexico, Colombia, and the United States, and enjoys singing an occasional concert of Classical German Lieder.
