heheh Luthienne...forget the image on the beach. It seems that sand gets everywhere no matter what care you take. I tried that in La union. There was one surfer who pulled out a trem harp and just kept blowing away like he was improvising. I pulled one out and jammed but it only took a couple of tunes and i got sand in already. How I managed to get it there ?? Probably the intoxicant.
Yes the blues harp may yert be the most portable musical instrument. You can take it hiking and doing other stuff. One thing .........its not only for peaceful or soft music. It can also hold its own ruckus in the right hands or mouth for that matter. hehehe.
I'm sure you can learn it alone but it will be faster if you get a tutor. i'm no pro but am always willing to share any little I know. Good luck.
