I know some people are going to say EVERYTHING, but I'm asking for some specific suggestions. For decades, it was all about performing for me, that's what drove me musically. I got to a point, where for various reasons (where I live, financial reasons, medical reasons, etc etc etc) my days on stage are over. In fact, its unlikely that I'll ever have an opportunity to play with other musicians again. When I realized this, my playing really took a hit, and I lost interest in it. But I miss playing. I need something to get me back into it. I'm trying to think of something to play that is fun just for the sake of playing, but short of an upright (which I cannot afford), I can't think of anything. Any suggestions on styles of music that seem to be more fun to play solo than others?
