Answer: The answer to the dominant musical types in the twenties would definitely be Jazz music.
Explanation: Jazz music exploded in the American scene in the twenties and led to a revolution in lifestyle, that was more of a carefree, more loose way of life. Jazz was popular among African Americans who frequently played this type of music in concerts and Bars, where largely bands would perform, before it could be played on radios, as it gravitated towards the white middle class.This way of life can be seen in Lyrics by Duke Ellington " i must have that man" which clearly shows that people in that era had embraced a more carefree lifestyle. Jazz had a touch of African tunes to it and was widely accompanied by instruments like the piano, saxophones, Harps and drum sets. It definitely revolutionized the American culture before the onset of the great depression.
