With a unique repertoire that combines classical horn literature with the ancient sounds of the shofar, he performs concerts, chamber music, and world premieres at the highest level. Whether as a soloist, orchestral musician, or chamber musician, Zemach combines technical mastery with expressive depth, opening up new acoustic perspectives for his audience. As a pioneer of the shofar in classical music and a dedicated performer at international festivals, he has established himself as a defining voice of his generation. He regularly performs recitals in a duo with pianist Prof. Dr. Jascha Nemtsov; they perform throughout Europe and will make their American debut in the coming season.

Even before graduating with a perfect grade of 1.0 from his studies with Prof. Christian Friedrich Dallmann at the Berlin University of the Arts, he was a scholarship recipient of the Lucerne Festival Academy, the Moritzburg Festival, and the Grafenegg Campus. Bar Zemach was selected as a Britten Pears Young Artist for the 2024–25 season. He served as principal horn with the Junge Deutsche Philharmonie and held temporary engagements with the Düsseldorf Symphony Orchestra and the Staatskapelle Berlin.
Since 2022, he has served as principal horn with the West-Eastern Divan Orchestra, performing, among other works, Bruckner’s Symphony No. 4 at the orchestra’s 25th-anniversary concert with Daniel Barenboim. Bar Zemach made his solo debut in Germany at both the Berlin Philharmonie and the Konzerthaus Berlin. His debut as the first shofar soloist to present a world premiere by Amir Shpilman with the Sinfonie Orchester Berlin was covered by The Jerusalem Post, the Jüdische Allgemeine, The Jewish Chronicle, and the B.Z., among others.

As a chamber musician, he has performed and recorded all over the world, from Israel to Germany to Taiwan. He has played with musicians such as Giora Feidman, who instilled in him a love for klezmer music and mentored him as a young artist. Their collaboration was documented in the ARTE documentary “Giora Feidman – The Clarinet as the Voice of Hope.” Bar Zemach has performed with the wind section of the Staatskapelle Berlin, with whom he recorded all of Richard Strauss’s wind serenades, as well as at festivals such as the Jerusalem Chamber Music Festival, Intonations in Berlin, the West Cork Chamber Music Festival, the International Days of Jewish Music, and the Jewish Culture Days Berlin. He is also a future artist-in-residence at festivals such as SHALOM-MUSIK.KOELN. With the Boulez Ensemble, he has collaborated with composers and conductors such as Matthias Pintscher and Jörg Widmann. He performs as a guest hornist with the Pacific Quintet.

As a pioneer, Bar Zemach has brought the shofar into the realm of classical music: in 2025, he performed the world premiere of a concerto for shofar and orchestra by Amir Shpilman, commissioned by Zukunft Klassik, at the Berlin Philharmonic. He also premiered a shofar concerto by Michael Wolpe at the Israeli festival Sound of the Desert (commissioned by the Goethe-Institut). Further appearances as a shofar soloist have taken him to the Nuremberg Symphony Orchestra, the Thuringia Philharmonic, the Israel Symphony Orchestra, and the St. Christopher Chamber Orchestra, among others.
