Thanks everyone! I've been doing Marty's version, it is also Drop D. Wow Many Moons, appreciate you sending that Clapton video. I wish the whole video was a close up of his neck. I am getting better with the Let It Be solo but on acoustic it's not quite the same.
Here is a chart for keys tween harp and guitar:
Music key —- Harmonica key
E —————– A
A —————– D
G —————– C
C —————– F
D —————– G
F —————– Bb
So choose your poison, you need 3 or 4 harps at about $50 each. The best thing about harp is it makes freight trains go by quicker, I always keep A,G,C & D in my console. When a good blues song comes on I can tell in a few seconds if the key of the harp is going to work. I strongly suggest it for a guitarist, it's fun, easy to learn, hard to sound sucky, lots of free tutorials on this interweb thingy. However, it's hard to hear the chord changes because the harp is loud! And if you have the sun roof open people at red lights always looked around where this this blues harp coming from? When they're about to spot me I stop blowing, then when they turn away I start playing again. Makes strangers laugh...
I took a couple of blues harp classes at the Chicago Old Town School of Folk Music. They were the only people that took the blues seriously. Once a week they had a for real, faux dive bar in the basement, you can bring beer, they had a paid pro drummer, rhythm and bass guitarists, and the special mics for blowing harp. Advanced students could perform and then were critiqued by the teacher, a famous blues harpist. This was last year. The thing that stuck out to me was that everyone was an old white guy. Even here we all skew older, maybe Griff is the youngest? I tried to get them to add more blues guitar classes but they said the blues is dead, just us few old guys! And these are Chicagoans saying this!
So seems like tomorrow is my last day here. I'm at the end of my 3rd month and thanks to the pandemic and being retired, I mined the site for a couple of hours every day and believe I have gleaned what I can for my level and have hit a headwind of the rest being too difficult for my 67 year old fingers. I miss acoustic in Open D. Thanks to the folks here I switched to Stringjoy strings and now want to do more acoustic. I have a Fender bar stool and play in the master bedroom's bathroom and wow, acoustically it sounds like Carnegie Hall. I appreciate all the great advice I received here. Maybe I'll come back in a few months in the near future.
Best,
Ned
