Before she moved to the United States, Mrs. Day was a piano teacher and an accompanist for a chorus at a music school.  She wrote an award winning series of articles giving a new, progressive method of teaching piano.  She was involved in educating other piano teachers.  Her students participated in piano competitions, festivals, and other events.

She uses classical pieces, traditional songs, jazz and standard exercises, resulting in a highly effective way of teaching piano. She believes that "Learning piano should not be boring!"
