Hey guys,
I'm the fretless bassist from the teenage band who played Sweet Child Of Mine at a local talent show. I posted it here awhile ago, got a few comments. Anyway, we will be playing on a live TV show in Oklahoma, playing 3 songs. We each have a 30 second "bumper" or solo, to show off our individual abilities. I have no idea what to play, honestly

Any suggestions for a 30 second fretless bass solo?
Thank you so much!
Ty
