I've been playing that 'C-chord-D' at the third fret for over 30 years and it makes a great sound when playing it as a passing chord. Thank You for the info.
Thanks. That A-shape triad with the higher D (which I had to try right away) has a nice light and sweet sound to it, even on my Yamaha Pacifica. I had to make sure it wasn't just the guitar ... Cheers.
