Ellen Beach Yaw (September 14, 1869 – September 9, 1947) was an American coloratura soprano, best known for her concert singing career. She had an extraordinary vocal range and could produce unusually high notes. Known as "Lark Ellen" or "The California Nightingale," she was reportedly the only known soprano of her era who could sing and sustain the D above high D. She was also able to trill in major thirds or fifths (trills usually involve rapidly alternating notes over an interval of a minor or major second).
Yaw was born in the small town of Boston, near Buffalo, New York (not Boston, Massachusetts, as is often stated), the daughter of Ambrose Yaw, who manufactured cow and sheep bells. Her family moved to Los Angeles when she was very young, but her father died when she was a small child, and the family was very poor.
Yaw began singing and composing songs as a child. She studied singing in America, first with her mother; then with Mrs. Torpadie, the wife of tenor Theodore Bjorksten; and then with Ernesto delle Salle. Yaw sang in concerts, beginning as a child in the 1880s, to make money to pay for singing lessons. Tours of the southern United States, California, England, Switzerland, and Germany followed, and on her return to America she gave a concert in Carnegie Hall in 1896. Yaw raised enough money through these concerts to study in Paris with Mathilde Marchesi and later coached with Alberto Randegger. She also sang several opera roles in the late 1890s, including Ophelia in Ambroise Thomas' Hamlet in Nice in 1897.
In 1898 and 1899, Yaw was singing in private concerts in London, and at one of these, at the home of Mrs. Fanny Ronalds, she so impressed Sir Arthur Sullivan that he prevailed upon the D'Oyly Carte Opera Company to cast her as the Sultana Zubedyah in his comic opera The Rose of Persia, which opened on November 29, 1899 at the Savoy Theatre in London. Sullivan went so far as to write a special high cadenza for her song "'Neath My Lattice," a cadenza that only she could sing. Yaw's first two nights were shaky, though the reviews were mixed, and both the music director, Francois Cellier, and Mrs. Carte advocated for her replacement. Sullivan at first agreed, writing in his diary on 2 December, "I told [Cellier] I was afraid [that Yaw] would not improve, that she hadn’t got it in her.... I don’t quite see what it’s all about — Miss Yaw is not keeping people out of the theatre as Cellier and the Cartes imply."
