Cantor Janet Ilene Roth


Cantor Roth came to the congregation in 1991. Since her arrival, the quality and variety of the musical experience, both during services, and on special occasions, has increased significantly. Cantor Roth participates in all aspects of congregational life including conducting services, directing the adult and children's choirs, teaching adult education and religious school students, and preparing children for bar/bat mitzvah. She continues to create artistic and musical programs that explore the vast range of the Jewish cultural experience. Keen on congregational participation during services and cultural programming, she has organized a Torah chanting and davening program that nurtures the knowledge and mastery of Jewish liturgical skills.

Cantor Roth received her undergraduate degree in Near Eastern Languages and Literature from Indiana University at Bloomington, a Master of Arts in Music from North Texas State University and a degree in Sacred Music with the Diploma of Hazzan from the Jewish Theological Seminary of America in New York. Cantor Roth lives with her family in Summit, New Jersey.

A message from the Cantor:

I have been fortunate to be able to take my greatest loves--Judaism and Music--and combine them into a fulfilling career as Cantor here at COS-SJCC. Being Cantor of COS-SJCC involves much more than just singing at services. I find myself immersed in so many aspects of synagogue life, including adult and children's choirs, religious school, b'nai mitzvah education, adult education, hospital visitations, cultural programs, concerts, family services, nursery school, the Interfaith Council, and life cycle events, to name a few.

I believe in upholding and maintaining our beautiful musical tradition, yet, at the same time, I like to look at current trends in Jewish music and prayer for possible ideas on how to integrate the spiritual and cultural aspects of Judaism even more creatively. Music is my path through the liturgy and to the divine. When I look at the text of a prayer-even one that is not sung-I hear music...for me it is the music that illuminates the text and fills me with emotion as we worship together. Through my singing I try to share my vision and emotion with the congregation.

I believe that our religious services have something for everyone...davening, chanting, melody, harmony, time to pray silently, time to listen, time to burst out into song...and even, occasionally, a little hazzanut--the art of interpretive expression of the liturgy. We encourage our members to participate in services by singing together, by chanting Torah, by leading from the bimah, by listening actively, and by being part of the process by which we seek to enhance our communal worship even further.

I'm happy to answer any questions you may have. Please contact me by email or phone at 908-273-8130.
