It's one of those times when the muse is hiding again. Best then to wait till I get the call, and the words / lines will just come along to later edit into the final piece.
I was talking yesterday that in the Blues poems I try to avoid too much of the traditional lines (cliches?) about the Levee, Delta etc. Since I am not here in the Deep South, or the Levee.
Instead I hope that I weave my own urban take into the lines, singing phrases that seem original and read right to the ear. Frequently some general bluesy tune is in my mind when writing, so the rhythm comes out in the lines.
Like all writers (poems or other) if I hear good line somewhere, or hear of a story thne I may adapt this into my work.
