In the prologue of Invisible Man, the narrator seeks light in his darkness by iluminating his hole with 1369 light bulbs.  The number is a tribute the the year 1936. 

That was when he moved to New York City and met a number of influential people during this time of the Harlem Renaissance.  Most notably, jazz poet, Langston Hughes.

Jazz Poetry began as a way to speak of jazz music and its musicians but Langston and others soon realized that it could be jazz…that jazz was more than music.  Making use of syncopation, repetition and the blues they gave birth to a new way of doing poetry…a jazz way.
