Una Bourne's musical abilities were evident early in life; she performed on piano in professional venues before her teens.
[4] "Miss Bourne has an excellent technique and plays with refinement and distinction," an English critic wrote of a performance at London's Bechstein Hall in 1906.
She also made player-piano rolls in the United States, and gave performances for women's clubs[8] and radio audiences.
[4] Bourne's art songs and compositions for piano are considered "light and dainty", and include March Grotesque, Petite Valse Caprice, Gavotte, Humoresque, and Wiegenlied, which was dedicated to Nellie Melba.
[9][10] Una Mabel Bourne lived for many years with her friend and colleague, soprano Mona McCaughey, who died in 1964.
