Please note that:
* Amy Beach was a prominent American composer and pianist.
* She lived and worked primarily in the United States.
* There is no mention in her biographies or historical records of her speaking another language.
However, as a highly educated and cultured woman of her time, it is possible that she had some exposure to other languages, perhaps for cultural or musical reasons. It's also possible that records of her language skills have not been preserved.
