Ursula Greville (1894 – 1991) was a British soprano and folksong singer, songwriter, writer and editor of The Sackbut (a critical music magazine).
[10] She was in a relationship with John Kenneth Curwen, the publisher of the magazine, and had no prior experience so the decision was seen as controversial.
[11] She also composed some songs which were published through her husband's company, Curwen Press.
[12] Greville was the recording engineer and part owner of Synchrophone Company, which was formed by Hans Knudsen in 1919 but purchased by Curwen in 1930.
[15] Greville engineered over one dozen records of Frank Newman playing the Christie Theatre organ at the Plaza Cinema (in Rugby, Great Britain) for Octacros.
The organ had been moved shortly before the recording which left Greville with a less than ideal location for placing a microphone.
