Montone confirmed afterwards that she has not yet signed a contract nor accepted the Philadelphia position.
If she were to accept the position, she would become the first woman principal horn in one of the major "Big Five" orchestras in nearly six decades, according to the Philadelphia Inquirer.
Last week, Montone told the St. Louis Post-Dispatch that she is reluctant to leave St. Louis. "With [music director David] Robertson here, it's a pretty amazingly good place to be right now," she said.
A spokesperson for the Philadelphia Orchestra did not immediately respond to a request for comment.
