British modernist composer Jonathan Harvey dies at 73

LONDON - Jonathan Harvey, a British modernist composer of operas and other works, has died at age 73.

Faber Music, which published Harvey's compositions, said he died Tuesday. He had suffered from motor neuron disease.

Harvey developed his style in the 1980s working at Pierre Boulez's Institute for Research and Coordination in Acoustics and Music in Paris. Fruits of that work were his tape piece "Mortuous Plango" and his fourth string quartet featuring live electronics.

Harvey's compositions have been featured at the BBC Proms in London, English National Opera, and the Dutch Opera. One of his last works was "Weltethos" for orchestra and chorus. It had its premiere performance at the Berlin Philharmonic last year.

He is survived by his wife and their son and daughter.
