I'm interested, especially if you can relate the lessons to well-known players and cover the options like holes and tunings. Why, other than to make more interesting publicity photos, would Little Walter use the chromatics? I don't have a chromatic and probably wouldn't buy one, but I'm very interested in blues harmonica evolution and figuring out what is going on in earlier recordings where all or most of the people with first-hand knowledge are now dead.
I get more from your commentary and ideas about what works to keep the music interesting and dynamic than from the licks. Keep that coming!
So in summary, please don't spend months on it, but I would appreciate learning more about the instrument through a several-weeks-long series.
Thanks for asking!
