The Romania-born pianist was named Commander of the British Empire (CBE) in the honours list of the UK, where he lives.
There are OBEs for the pianist Malcolm Martineau and conductor Steuart Bedford, as well as David Joseph, chair and chief executive of Universal Music.
Others honoured include Catherine Arlidge, a violinist in the City of Birmingham Symphony Orchestra who devotes her free time to engaging children in classical music. Catherine created The Stringcredibles, a string quartet formed of fellow-CBSO musicians which runs creative workshops, performances and other events for young people.
She receives the MBE, as do Michael McCarthy and Michael Rafferty, founders and joint Artistic Directors of contemporary opera company Music Theatre Wales. Also in the MBE list are the violinist Alina Ibragimova and the Royal Liverpool Philharmonic supporter Milena Lady Grenfell-Baines. The indefatigable Milena, 86, was one of the 669 children rescued from the Nazis by Sir Nicholas Winton in 1939.
