The Weiner Ensemble was founded in September 2014 from graduates and doctoral students of the Budapest Franz Liszt Academy of Music under professional supervision by professor Márta Gulyás. The primal aim of them is to draw the attention of the audience on a wide repertoire of pieces from Baroque solo pieces through 20th century compositions up to contemporary pieces, written for an individual setting of instruments. These pieces are performed usually by a “Pierrot ensemble”, named after the twentieth-century composer Arnold Schoenberg’s seminal work Pierrot Lunaire. In 2015 the ensemble took the name of composer Leo Weiner approval of the Leo Weiner Foundation.

In August 2016 Weiner Ensemble has received the 3rd prize at the Orlando International Chamber Music Competition in Kerkrade, the Netherlands.
