If the visual of the piano helps you, or you want to see the chords and scales/modes written out as they are played, the videos by Tony Winston are spectacular! I will be watching more. He has different levels of the same piece.

In particular, no specific African musical form can be identified as the single direct ancestor of the blues. However many blues elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa. That blue notes pre-date their use in blues and have an African origin is attested by English composer Samuel Coleridge-Taylor's "A Negro Love Song", from his The African Suite for Piano composed in 1898, which contains blue third and seventh notes.
