Dvořák was influenced not only by music he had heard, but by what he had seen, in America. He wrote that he would not have composed his American pieces as he had, if he had not seen America. It has been said that Dvořák was inspired by the American "wide open spaces" such as prairies he may have seen on his trip to Iowa in the summer of 1893. Notices about several performances of the symphony include the phrase "wide open spaces" about what inspired the symphony and/or about the feelings it conveys to listeners.
