What is NOT true about Dvorák's symphony No. 9 in E minor "From the New World?"

Dvořák's Symphony No. 9, commonly referred to as the "New World Symphony," does indeed reflect his experiences in the United States and is inspired by American folk music, along with incorporating elements of African-American spirituals. However, the assertion that it is Dvořák's most nationalist piece, particularly emphasizing his Bohemian identity, is not accurate. Dvořák was deeply influenced by his exposure to American musical styles during his time in the United States, which resulted in this symphony being more of a fusion of various influences rather than a pure representation of his Bohemian nationalism.

In contrast, the other statements uphold widely accepted interpretations of the symphony. It draws inspiration from the folk music of America, particularly through the themes that evoke the feeling of the American landscape and cultural heritage, along with elements from African-American spirituals that Dvořák admired. Thus, the characterization of the piece as his most nationalist work does not align with the broader understanding of its influences and Dvořák's intentions during its composition.
