Hi @AstridHandbikebee63 and @HarpinBobbyMcB,
An exercise that I posted here on the forum that is somewhat challenging but is great to work on getting clean single notes and controlled, accurate bends in the lower half of the blues harp, is something that you both might enjoy trying to master. 
Do not get discouraged if you cannot play it immediately – and be sure to start learning it slowly to improve your bending skills and ability to play clean single notes. All sorts of variations of this exercise are possible, so feel free to modify it as you wish. 
Regards,
