Own trumpet and all that, but yes, I feel that I have made some progress an innovation with what I can do on guitar and mandolin, and learned to use my somewhat untuneful and hard-to-control voice to least disadvantage. It's one of the reasons I get so cross about those who would impose barriers to entry to folk music in the name of quality control.

Whether I can actually help anyone else improve is a different question. I'd encourage them to try, but I'm not sure it's my place to tell them how to achieve that, they are them and I am me. I will sometimes suggest chord sequences if I see someone oversimplifying, but many do not want to know, and indeed in many cases the choice between a D or a Bm or an A or an F#m, or a series of shifts within the FGC sequence or sticking to an Em is arbitrary.

I don't know what to do about people with no timing, however.
