Hi jomac, welcome. Resonators are great, they have that wonderful throaty sound and are
loud. The resonator itself, that round metal thing, is like a speaker, and was invented so that the rhythm guitar could be heard in the band.
I'm assuming you didn't buy the square neck resonator, which is played lying flat on your lap with a stee bar. If you bought a regular guitar with resonator, anything can be played on it, but of course country or blues sounds the most appropriate. I used my resonator on quite a few of the lessons here. They sound great with
slide.
There are many sites out there that specialize in resonators ... do a quick search and you'll see what I mean.
