This will probably grab some flak, but...............

Take the time to learn a bit of piano. Have your kids do the same if they show any interest at all in music. The keyboard of a piano is the most visual aid you can have in learning and understanding music theory. When you read a text the piano makes it easier to simply apply what is being said....you can both see and hear immediately what is happening. Whether you are counting half steps or whole, or working out a chord structure.....hell, virtually anything you do.....you can both see how the "action" takes place and hear what the sound result is. Doing this will also train your ear to hear better and we'd probably reduce the "chord requests" around here by about 75%!

I'm a lousy guitar player. I enjoy myself, but have never worked too hard at it. But I am very serious in suggesting the above to those that have a hard time hearing chords and progressions. It makes a lot of difference.
