Born in Israel, Yair Kless began playing the violin at the early age. He graduated from Tel Aviv Music Academy, under the tutelage of Israel Amidan.
Following a recommendation from Nathan Milstein, Yair moved to Brussels to study with Prof. Andre Gertler in the Royal conservatory and Chapelle- Musicale Reine-Elizabeth, graduating with the highest distinction in both instrumental and chamber music. Yair quickly became a well known soloist, performer and chamber player. His vast repertoire ranges from Baroque to Modern, including premieres of works, some of which were written especially for or dedicated to him.
