Hey Bill, One more idea for you:
The Lick of the Week is a super way to train your ear. This week is Lick of the Week #53 and it is one of the easier ones. Take a listen and see if you can figure it out; it has only a single 2 hole bend, the rest are unbent notes. Give it a go. Be sure to make use of the slow down feature to help you to hear the notes better. Again don’t hesitate to ask for help.
If you want I can show you some of the others that are easier.
