 During the later 1880s, while on leave from Clara Schumann's school, Borwick had met the baritone Harry Plunket Greene while playing one evening at Arthur Chappell's house in London.Greene had been at Clifton College with Borwick's brother, and a friendship grew up between them.He made his debut at the Museum concerts in Frankfurt in Beethoven's "Emperor" concerto in November 1889, and in the same month at Strasbourg under the direction of Franz Stockhausen (a pupil of Alkan) in that concerto and with pieces by Chopin (a Nocturne) and Liszt (the Paganini Études).
