Yaniv Dinur

Milwaukee Symphony Orchestra Associate Conductor

Yaniv Dinur is the Associate Conductor of the Mikee Symphony Orchestra and the newly appointed Music Director of the New Bedford Symphony in Massachusetts. He made his conducting debut at the age of 19 with the National Symphony Orchestra of Ireland, a performance that resulted in multiple return engagements with the NSO. Following his European debut, he was invited to perform with the Israel Camerata, making him the youngest conductor ever to conduct an orchestra in Israel.

He since conducted the Israel Philharmonic Orchestra, Jerusalem Symphony, Houston Symphony, Louisiana Philharmonic, New World Symphony, San Antonio Symphony, Orchestra Giovanile Italiana, Orchestra di Padova e del Veneto, Orchestra Sinfonica Abruzzese, Pomeriggi Musicali in Milan, Solisti di Perugia, Torino Philharmonic, Portugal Symphony Orchestra, Sofia Festival Orchestra, State Orchestra of St. Petersburg, Orquesta Filarmónica de la UNAM in Mexico, and the National Arts Centre Orchestra in Ottawa.

Mr. Dinur is the winner of numerous awards, among them the 2017 and 2016 Solti Foundation U.S. Career Assistance Awards, 2nd Prize at the 2009 Mata International Conducting Competition in Mexico, and the Yuri Ahronovitch 1st Prize in the 2005 Aviv Conducting Competition in Israel. He was chosen by the League of American Orchestras to be a featured conductor in the 2011 Bruno Walter Conducting Preview, and he is a recipient of the America-Israel Cultural Foundation and the Zubin Mehta Scholarship Endowment. He has worked closely with such world-class musicians as Lorin Maazel, Michael Tilson Thomas, Edo de Waart, Pinchas Zukerman, Itzhak Perlman, and Kurt Masur.

Yaniv Dinur is also an accomplished pianist and a passionate music educator who is committed to exposing new audiences to classical music. Since joining the Milwaukee Symphony, he has performed with the MSO in unusual venues such as an industrial design factory, an unfinished office building, and a planetarium in concerts created especially for young professionals. He has also performed in troubled neighborhoods in Milwaukee, bringing orchestral music to people who do not usually have access to it. He often gives pre-concert talks and lectures at different venues around town, in which he incorporates live demonstrations on the piano, aiming to reveal surprising connections between pieces, composers, and eras. In addition, he created a series of short, fun YouTube videos that give a deeper look into musical pieces of all genres.

Mr. Dinur was born and raised in Jerusalem, where he studied piano with his aunt, Olga Shachar, and later with Alexander Tamir, Tatiana Alexanderov, and Mark Dukelsky. He studied conducting with Dr. Evgeny Zirlin and Prof. Mendi Rodan at the Jerusalem Academy of Music and Dance. In 2007, he moved to the United States to study with Prof. Kenneth Kiesler at the University of Michigan, where he earned his Doctorate in Orchestral Conducting.


Under the guidance of Maestro Dinur, pianists learn how to navigate the professional orchestra rehearsal – communicating with the conductor, coordinating editions and rehearsal markings, and reviewing proper rehearsal and performance etiquette. Each semifinalist meets privately with Mr. Dinur and performs with him and a chamber ensemble of orchestral musicians. Finalists rehearse full concertos with Mr. Dinur and a chamber ensemble prior to rehearsing and performing with the full Milwaukee Symphony Orchestra under the baton of Mr. Dinur.

Maestro Dinur’s master classes on
styles and movements are open to the public during the competition week’s concurrent
 music festival.
