Artful Codger, if *only* I could be as brief and precise as you in my explanation of re-entrant tuning!

And thank you so much for your last paragraph. It was to find out that sort of info that I started the thread. Great.

s&r (or anyone), could you explain "My dog has fleas" as a way of knowing uke tuning, please? (I'm assuming it is not tuned M-D-H-F!).
