Klezmer is the music from the Yiddish culture, language spoken by the numerous European Jewish Community, placed in a large portion of the Central and Eastern Europe along the Second Millennium; from Germany up to Russia, From Baltic Sea to Black Sea.

The word Klezmer derives from yiddish כלזמיר, (see video "History of Yiddish") ethimologically from Hebrew k'li zemer כלי זמר, "music instrument "; the word "kli" linked to "instrument, tool or container " and the word "zemer"singing, sound and worshipping".

Originally, word klezmer refers to music instruments with which this music was played. Nevertheless, later on, this applied both to the style and the musicians themselves, now called klezmorim.

Along the Jewish history music always had a dominant role

Torah, Hebrew word that means learning, instruction or, more specifically, Law; which covers the first five books of the Bible (which are called by Chrsitians Pentateuco), is not read but sung. Celebrations and funerals were sung along, rabbis were able to keep the tradition of music in every temple and religious service; after the destruction of the Second Temple of Jerusalem, Jews continued with this tradition in the exile, called “diaspora".
 
Klezmer is easily recognized by its characteristic expressive tunes, close to human voice, inclusion of laughs, crying and howling. Even when there is no accurate register, Klezmer music is born little after the turn of the Second Millennium.

At the beginning, musicians went around large extensions of land working as street performers, going from village to village and performing in taverns, street, and theaters, weddings from Jews and Christians and family parties. From these circumstances, it is born the street and occasional musician, which gives life to village’s celebrations, bringing tunes that might appear as nostalgic but, on the contrary, are the highest expression of the joy for life, as it is affirmed by the name of some styles, such as freilaj (joyful).
