In June 1900, Weber was almost 21 and living with her parents and two sisters at 1717 Fremont Street, Allegheny, Pennsylvania, where she was a music student. By April 1903, Weber was performing as a soprano singer and pianist. She toured the United States as a concert pianist until her final performance in Charleston, South Carolina, a year later. After a piano key broke during a recital, Weber retired from the concert stage, having lost her nerve to play in public.
