First, what is Klezmer?

Klezmer, short for "Klei Zemer" in Hebrew and Yiddish
means "Musical Instruments."

Jewish musicians developed klezmer music in Eastern Europe. Many times, klezmer music was played at weddings and Bar mitzvahs, in the house yard or somewhere out doors. Klezmer fests and other Jewish celebrations took place in the streets.

To prevent the need for electric power, klezmer bands used acoustic instruments.

The typical klezmer instruments included clarinet, violin, accordion, grand bass and acoustic guitar.
Through the years when Jews were oppressed in Europe, klezmer music was not played much until it was almost forgotten.
