embraced jazz music.

Explanation:

During the 1920s-1930s, jazz grew in mainstream popularity, becoming a defining cultural sound of the era (the "Jazz Age"). Spirituals predate this period, ragtime was a precursor not universally rejected, and claims of credit were not a widespread core result of its development. The key outcome was broad public acceptance and embrace of the genre.

Answer:

embraced jazz music.
