Her father, Arthur Shinner, was head of the Cheltenham Original Brewery and an amateur musician; he supported her musical education.
[1][2] Shinner's debut in London after completing her studies was in 1882 at Kensington Town Hall, playing the Violin Sonata No.
A critic wrote: "Her playing, besides being perfect in every technical respect, is marked by an extraordinary degree of intelligence and true artistic refinement" (The Pall Mall Gazette, 12 June 1882).
[1] In February 1884 she replaced Wilma Norman-Neruda, who was unwell, in a quartet in a Saturday "Pops" Concert in St James's Hall; the event was successful, and made her well known to the public.
[1] She taught violin in the Ladies' Department of King's College London.
