Christopher,
Thank you so much for your reply! Yes, I have completed your tutorials on music notation, as well as those by Lisa. I do remember learning some of the basics many years ago; I will just need to continue to brush up on reading music and then apply that to what I am learning on the guitar.
So far, I am just using the basic Treble Clef music (melodies) in the hymnal; I will check the sources you mentioned for other ideas on chord voicings.
Thank you again for your help and I appreciate all your efforts!
