I've stuck a bit on Soundcloud. It's a private track and I don't know if a simple, direct link to it will work or it will just deny access? Please say so, if it doesn't. It would be nice to know for future reference. It obviously works for me and I don't want to set it to 'public'. I'll try and find another site to upload it to, if that's the case. I'm open to suggestions on that front, too.
I ended up with (I think): -
C, G (1st inv), Am, Em, F, G, C (2nd inv) F.
C, G (1st inv), Em, Am (2nd inv), Dm, C, Am, G
I like the sound of it, but it's very plain. I put in some extra notes an octave lower to fill the sound out a bit. I might even have inadvertently created some of those elusive chords! Hopefully, using some of the stuff you all have suggested, I'll try and do a version where I can squeeze some chords inbetween them.
Thanks once again for your time, everyone. I've learnt some new things these past few days because of you all.
