In 1938 Egon Wellesz had to leave his hometown of Vienna where he was a professor of musicology .
He emigrated to England where he lived until his death, apart from temporary teaching positions in the USA and in Edinburgh.
As a musicologist, he studied Byzantine music which in turn influenced his work as a composer, for instance in the pentatonic melodics of his voice parts. A pupil of Schoenberg, he developed from a style following the influences of Reger, Mahler, Pfitzner and Schoenberg to an original synthesis of expressionist, neo-classicist and archaic elementsÂ *Â His stage works are primarily focussed on Greek mythology. In 1931, Clemens Krauss staged his most important work, the two-act opera Die BakchantinnenÂ (The Bakchantines), with great success in Vienna. His operas are ritualistic, quasi-oratoric stage works built upon massive choral blocks
