Ilya Friedberg, born into a Jewish, musical family in 1982, is a classical pianist from Moscow, Russia. Friedberg’s father, Michael Davidovich Friedberg, worked as a mathematician and was a member of the scientific research staff at the High Temperatures Institute of the Academy of Sciences. His mother, Alla Yanovsky, is a piano teacher from whom Friedberg received his first musical experience.

Friedberg’s older siblings all received lessons from Mrs. Friedberg, who decided not to teach him, the youngest child of four. Therefore, he started observing her teaching all by himself and learning things on his own accord. Remarkably, the self-taught child was admitted to the Gnessin State Musical College at the age of 6.

In 1992, the family moved to Jerusalem, Israel, where Friedberg was admitted to the studio of Luissa Yoffe at the age of thirteen. There, he enjoyed his first public success, which included tours to Italy, Ukraine, and Russia.

After meeting and studying with Vladimir Ashkenazi, Friedberg pursued his higher education in the USA. There, he earned his doctorate degree through the guidance of Menahem Pressler, serving as his teaching assistant from 2013 to 2018. Additionally, he participated in extensive private study with distinguished artists and pedagogues, including Angela Cheng (Oberlin), Jeff Cohen (Manhattan), Alan Chow (Northwestern), Sanford Margolis (Oberlin), Alvin Chow (Oberlin), Asaf Zohar (Tel Aviv University). Friedberg has also studied chamber music with prominent musicians, specifically Janos Starker, Menahem Pressler and Jamie Laredo.

Friedberg’s performance career and extensive music education has taken him to multiple locations around the globe, including Europe, Russia, Israel, and the United States. As an active soloist and chamber musician, he has performed with prominent musicians, such as Uriel Segal, Carol Vaness, Timothy Noble, Mark Kaplan, Joe Swensen, Atar Arad, Yuval Yaron, Alexander Buzlov, Daniel Austrich, Alyssa Margulis, Peter Takacs, Pacifica Quartet, Gil Apap, and Jamie Laredo.

Friedberg currently serves on the faculty at Music Institute of Chicago, and of Summer String Academy at Bloomington, Indiana, Sonad Chamber Music at New Hampshire, and New Harmony Music Festival.
