Answer:
Ragtime & Tin Pan Alley
Step-by-step explanation:
The early popular American styles of music included the "Tin Pan Alley" and the "Ragtime."
The "Tin Pan Alley" was an American style of music derived from a street name in New York City. There was a growing demand for music at this time and songwriters were strained to meet such demand.
On the other hand, the "Ragtime" was a distinctive music used for dancing. It was considered a "black music" of the Americans due to the similarity of style to the African's banjos. The development of this genre influenced the birth of jazz music.
