As mentioned the 2 draw bend is an important bend and it isn’t a bad place to try bending. The bend is controlled by the shape of your mouth and movement of your tongue, a good starting point is to try to go from a clean (non bent) note into the bent note by pronouncing certain words – of course all this is done while breathing in, so practice talking on a back breath.
Try saying ‘dwaa’ into ‘dwar’ or ‘yaa’ into ‘your’ or ‘ee’ into ‘or’ (donkey style!) also think about making your mouth feel long and dropping your jaw a little. If you can get a bit of a bend, try to feel it and control it with your tongue and mouth.
