This is a topic within jazz piano education that I get asked about A LOT! For good reason too. Fortunately, most of the work I get actually come with playing with singers. I've excelled at this through out my career from playing in a church for a long time. In church, I've had to accompany singers in all sorts of styles, genres and situations. Let me tell you, the path is not easy. I'm confident these basics will get you started on the right path. Enjoy!
