John Weeks Moore, Complete Encyclopaedia of Music… (1880)
“ Bates, Mrs., wife of Joah Bates, was a celebrated female singer. She was remarkable for her fine and clear articulation, which has been compared to that of Garrick in acting. She is said, by a professor of great reputation, to have possessed vast natural requisites for a singer, to which was added high cultivation. She studied Handel with that great judge and enthusiastic admirer of his compositions, the late Mr. Bates, her husband, and the Italian school with Sacchini. ”
