For those of us who 'grew up' singing and playing an instrument at the same time, it seems very natural ... but to someone who hasn't done it, I understand it can be daunting and confusing at first ...

Rico - a suggestion - when you first try it, if you haven't already, try playing just left hand chord changes with the style as you sing ... don't be concerned about playing anything with your right hand ... that will come as you get used to it ...
