About Historical Black American English
In the United States you can sometimes hear the dialect known as Black English. Black English is also known as African-American English. According to Wikipedia it's "the set of English dialects primarily spoken by most black people in North America; most commonly, it refers to a dialect continuum ranging from African-American Vernacular English to a more standard English."
On Mama Lisa's World, we refer to the dialect that you'll sometimes find in older African-American literature as "Historical Black American English" to distinguish it from what's spoken today. We added "American" so that our international audience will know at a glance where it was spoken. Most of these songs and rhymes date back over a century.
