The Spectrum Duo
Spectrum Duo is the husband-wife team of pianist Robert Sacks
and violinist Vivienne Venderley. Since meeting in the early 1980's, they have
performed extensively together as a Duo and as founding members of the Spectrum
Trio, and individually as soloists. Both
are conservatory-trained, and bring a wealth of knowledge and experience to
their musical endeavors.
1987, Ms. Venderley and Mr. Sacks
have resided in Naperville,
IL, and each operates a full-time
teaching studio. While their studios are
separate entities, Ms. Venderley and Mr. Sacks
share a common goal: to make a positive
contribution to the musical life of their community. They teach students across a wide range of
ages and skill levels, and believe that any student who is committed and
enthusiastic can accomplish great things.
String and piano students appear on joint recitals, which are held three
times each school year—typically November, March and June. Students have opportunities to play both
solos and ensembles on these programs, which are currently held at Our
Saviour’s Lutheran Church in Naperville.
Students with the ability and desire are also encouraged to compete in
and Mr. Sacks have performed chamber music
regularly since locating in Naperville,
both as a Duo and with the Spectrum Trio, which adds the talents of cellist
Edward Moore. They have presented recital programs at various local colleges, libraries and
cultural centers, and have been featured on radio broadcasts and local cable
television. From 2004-13, they served on
the faculty of the OPUS Chamber Music Camp in Lisle, IL, as chamber coaches and
clinicians. In addition, they have
contributed their talents to many weddings, social gatherings and business
Spectrum Duo has developed a school assembly program to introduce children to
the pleasures of chamber music. Please
