David Ezra Okonşar (pronounced Okonschar) (born 20 October 1961, Istanbul is a Turkish-Belgian (double nationality) pianist, composer, conductor, writer and educator. He was previously known as "Mehmet Okonşar".
David Ezra Okonşar was born in Istanbul (Turkey) with the first name "Mehmet" and lived in Paris during his first schooling. He started studying piano at the National Conservatory of Ankara, with Nimet Karatekin and Necil Kazim Akses. Thanks to the rich resources the Ankara Conservatory then possessed and the Médiatheque of the Centre Culturel Français d'Ankara, he grew up studying the music of Pierre Boulez, Edgar Varėse, Olivier Messiaen and Pierre Schaeffer, composers which would have a strong influence on him.
After about a year and half studying at the Ankara Conservatory, the family moved to Belgium where he entered the class of Jean-Claude Vanden Eynden at the Brussels Royal Conservatory of Music. Vanden Eynden, who ill entirely re-shape the keyboard technique of Okonşar, is a dedicated follower of the style of Eduardo del Pueyo.
A change of Government in Turkey and the political turbulences of 1977 forced Okonşar family to return to Ankara. Back at the Ankara Conservatory he is put in the class of Gülay Uğurata for the piano and of Nevit Kodalli for musical composition. Okonşar did not attend with any assiduity in either class.
During this period he connected on both friendly and professional basis with the pianist and conductor Selman Ada. From this friendship he learned the basics of the keyboard principles of Pierre Sancan of whom Selman Ada has been a student.
Just before the military coup of 1980 the Okonşar family returned to Belgium. He resumed studying with Jean-Claude Vanden Eynden. In 1980 Okonşar was rewarded the Premier Prix avec Distinction. His program included the Dante Sonata by Liszt. His studies continued after the sudden death of his father with a special scholarship and he got the  de Piano Avec la plus Grande Distinction, Premier Nommé in 1986 by performing the Piano Concerto Op. 42 by Arnold Schoenberg.
At the end of his piano studies, Okonşar had the privilege of working with one of the greatest composers of Belgium: Madame Jacqueline Fontyn. He also studied with a pupil of Messiaen, Claude Ballif. In 1989 he gets his degrees in Composition-Orchestration from the Royal Conservatory of Music of Brussels.
He endorsed the Belgian citizenship in 1992 but at the same time the President Suleyman Demirel of Turkey rewarded him with the title "State Artist of the Turkish Republic". Therefore Okonsar will settle in Turkey with his wife Lale Okonşar, painter.
Okonşar works now from Turkey on a busy schedule concertizing, composing, writing and teaching. He owns and manages a CD label exclusive to his own recordings, LMO-Records, and a publishing company "inventor-musicæ."
In August 2014, he took the first name(s): David Ezra.
His international career began with the first prize at the International Young Virtuoses Competition of Antwerp in 1982. His orchestral début was the Third Concerto by Rachmaninoff performed at the deSingel Concert Hall in Antwerp. His other prizes are: Paris, 1989, "J. S. Bach" at the Salle Gaveau: second prize; 1990, Rome, Association Chopin "Premio Etruria": first prize; and 1991, United States, Utah, the sixth prize at the "Gina Bachauer International Piano Competition".

His researches on music and technology were presented in a lecture at the Yamaha headquarters in Hamamatsu, Japan. Okonşar wrote and presented a documentary series on the National Television Broadcast of Turkey, the T.R.T.
Okonşar is a published writer in several music related periodicals in Turkey. His articles published in Andante the most important Turkish periodical on classical music, were featuring imaginary interviews with "Mephisto" on the subject of the global decadence of the quality of classical music, in Turkey and in the world, a subject often worked on by Okonşar. His other published subjects are mainly about musical composition, analysis, music history. Okonşar publishes also in English and French.
His repertoire encompasses a range from the early 17th. century ("The Fitzwilliam Virginal Book") including among others Orlando Gibbons and Giles Farnaby and extends to late 20th. century with the works by Karlheinz Stockhausen and Witold Lutoslawski. Notable works in this repertoire are: J.S. Bach "The Art of Fugue" performed on organ (or piano) and harpsichord; the Goldberg Variations, the integrale of Well-tempered Keyboard.
Okonşar has performed recitals featuring the complete piano works by Arnold Schoenberg, Alban Berg and Anton Webern. Despite he refuses all sort of "musical specialization", his repertoire is heavily on the "modern" side with Igor Stravinsky "Three Movements of Petrouchka" the "Sequenza" for the piano by Luciano Berio and the Klavierstücke by Karlheinz Stockhausen.

The compositions by Okonşar were from the beginning exploring unusual ensembles in an avant-garde line. During the eighties atonal (free) Jazz specially by Cecil Taylor and the intricate voicings by Bill Evans had strong impact on the total serialism Okonşar always used. Other extra-serialist influences are Krzysztof Penderecki, Iannis Xenakis and György Ligeti.
The electronic works created in the fifties and early sixties by Ligeti, Karlheinz Stockhausen, Xenakis, Henri Pousseur and others created a new and previously unheard approach to orchestration. The sound possibilities of the classical orchestra started to be conceptualized by the composers in terms of "sound envelopes", "sound filters and formants. Okonşar followed a similar path in his orchestrations, in the nineties.
The music by Okonşar is extremely structuralist and calls for an analytical approach. This structuralism is presented in the finished score in a very detailed, complex and refined musical écriture.
