Roger Chase (born in London in 1953) is a British violist who currently teaches at the Chicago College of Performing Arts at Roosevelt University.
He is the current owner of the 1717 Montagnana viola, which is the instrument that Tertis used during the height of his performing career, originally acquired in Paris when it was in pieces.
Since then, he has played as a soloist or chamber musician in major cities in the UK, US, Canada, Australia, Japan, India, and all of Western Europe.
He has played as guest principal violist with every major British orchestra and many others in Europe and North America, including the Berlin Philharmonic.
Viola concertos have been written for Chase by Richard Harvey, Jonathan Lloyd, and Francis Holmes.
