OK, tonight I finally got it.  A blues piece that's got all the parts;  it's got the rhythm.  it sounds good.  turnarounds, several bass lines, some decent improv.  A blues in E minor.  Good old E.  Played it on my little cheapo oldie nylon stringed classical guitar from Japan that cost about a hundred bucks.  A little 3/4 scale student model with the same strings since 1998.  
I'll record it sometime and put it online.  For me it's an achievement.
I really like my little cheapie nylon guitar!
