About the Directors



Diane Sare, managing director

Diane Sare grew up in Maine, in a musical family of scientists and doctors. Her mother, a biochemist, played the clarinet and piano, as well as running the Arcady Music Festival in Bar Harbor. Her father, a medical doctor, played the trumpet, and they were all regulars in the town band that played every summer on the Village Green.

Diane went on to study music education and trombone performance at New England Conservatory in Boston, during which time she met her husband Christopher, as well as associates of Lyndon LaRouche and the Schiller Institute. 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 the Schiller Institute since that time.

In the 1990’s, Diane directed the chorus in the Schiller Institute’s Washington D.C. production of Through the Years, a play written by Civil Rights Movement heroine Amelia Boynton Robinson, which had over 20 African-American Spirituals in it. The renowned accompanist and vocal coach, Sylvia Olden Lee, became Diane’s teacher and mentor in the performance of Spirituals during this time.

In 2014, Diane founded the Schiller Institute New York City Chorus, and is currently the Chorus's Chairman of the Board of Trustees.


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 LaRouche 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.


John Scialdone, secretary-treasurer

Son of Neapolitan and Sicilian immigrants, John Scialdone was raised on the accordion and the space program in the Finger Lakes region of New York. A piano technician for over 35 years, and a private pilot since age 16, John is Secretary-Treasurer and sings in the baritone section of the Schiller Institute NYC Chorus. He is married to Margaret, an avid pianist since age 5, who sings in the alto section.
