Vangelis, the Greek composer whose rousing electronic theme music for the Oscar-winning 1981 film Chariots of Fire became one of the most loved movie scores, has died at the age of 79.

The law firm representing the composer said he died late on Tuesday, without giving a cause of death.

In a post on Twitter, Greek Prime Minister Kyriakos Mitsotakis called Vangelis “a pioneer of the electronic sound”.

“He began his long journey on the Chariots of Fire. From there he will always send us his notes,” Mitsotakis wrote.

“Ad astra, Vangelis” - Latin for “to the stars” — tweeted Nasa, saying Vangelis contributed scores to its explorations to Jupiter.

Born Evangelos Odysseas Papathanassiou in 1943, the young Vangelis developed an early interest in music and experiments with sounds produced by banging pots and pans or fixing nails, glasses and other objects to the strings of his parents’ piano.

He absorbed the tones of Greek folk songs and Orthodox Christian choral music, but he had no formal musical training, which he later said had helped save his sense of creativity.

After a start with local rock bands, Vangelis left for Paris at the age of 25, joining an exodus of young artists following a 1967 coup that installed a military junta in Greece.

Despite enjoying success in the European “prog rock” scene of the early 1970s with Aphrodite’s Child, a band he formed with fellow Greek musician Demis Roussos, Vangelis was uncomfortable with the expectations on a commercial performing artist and largely retreated to the recording studio in London.

It was there that he wrote the score for Chariots of Fire, the story of the triumph of a group of British runners at the 1924 Olympic Games.
