Why is it significant that Zitkala-Sa trained at the New England conservatory of music?

Zitkála-Šá (Lakota for Red Bird;[1] February 22, 1876 – January 26, 1938), also known by her missionary-given and later married name Gertrude Simmons Bonnin, was a Yankton Dakota writer, editor, translator, musician, educator, and political activist. She wrote several works chronicling her struggles with cultural identity and the pull between the majority culture in which she was educated and the Dakota culture into which she was born and raised. Her later books were among the first works to bring traditional Native American stories to a widespread white English-speaking readership, and she has been noted as one of the most influential Native American activists of the 20th century.
