Wow! Thank you all so much! I got the G/D because I thought if I ever learned to play some tunes they were, a lot, in G or D and if I every sang, fok songs or hymns, those keys seemed comfortable. And there is also the added point, I just did it without a tremendous amount of thought. The tab systmes I will look at and see how they fit when I get the instrument. I have also tried harmonicas over time and use the harmonic tab some and the relation to that seems to help me pictue in my mind what I am doing. Anyway, thanks for the input and I look forward to the journey! Blessings
