Final answer:
The term for the fusion of West African and Black American music is 'African American music'. This includes genres like blues, jazz, and gospel, which often feature syncopated rhythms and blue notes. Stephen Foster's work and African American spirituals are examples of this cultural blend.
Step-by-step explanation:
The term used to describe the fusion of West African music with Black American music is often simply referred to as African American music. This broad term encompasses a variety of genres and styles that have resulted from the melding of these two rich musical traditions. The influence of West African music is evident in the use of syncopated rhythms, call-and-response patterns, and blue notes, which have become fundamental aspects of genres such as the blues, jazz, and gospel.
An example of this fusion can be seen in the works of Stephen Foster, known as "America's Original Pop Star", who combined his exposure to the music of African American boatmen and his classical training under a German music teacher. This blend of African and European influences established a precedent that has influenced many other music genres, including country, R&B, rock n' roll, and hip hop.
In addition to Stephen Foster's era, African American spiritual songs and lined-out hymnody are also significant contributions that reflect this cultural fusion, highlighting elements from West African musicality infused with American and European hymn tunes, leading to a rich tapestry that laid the groundwork for various forms of American music that followed.
