Re: Songs for busking with out backing
I myself am very good at playing by ear. I hear a tune and it just comes out. Improvising on such, not so fluent.
Anyway, I'd play anything and everything that enters your mind. Dont be afraid to pop out some current pop tunes along with whatever jolts your interest. Be more creative on your own and impress those listening. Go with whatever flow the people who bother to stop and listen are wanting to hear. Try to get a smile out of someone.
If your not there yet, dont embarrass yourself.
Play with honesty.
One of my most favorite "skits" I ever saw on SNL was Branford Marsalis playing on the street with his baby in a car seat at his feet. That was in the late 80s. Man Im old. I think that was when he was touring with Sting and Kenny Kirkland.
