I've been writing a little guitar thing. With a combination of messing about on my keyboard and playing guitar I've come up with this...
High b ----0-----2-0--|----0-----2-0--|----0-----2-0--|----0-----2-0--|
g --2-----2-----2|--2-----2-----2|--2-----2-----2|--2-----2-----2|
Low d 0-----0--------|2-----2--------|4-----4--------|4-----4--------|
Chord G A B B
The chords are guess work from badly playing 2 handed keyboard and guessing what might sound ok, as I don't have 2 guitars on me. From musical knowledge it should be right. It's a bit straight though, you'd probably want to play with the B chord a bit, maybe 7th it up and change the last bar of music.
The way I was playing the main bit is all pretty much straight with all notes an 1/8ths of a bar, so all semi-crotchets in 4/4 time I think. It's been a long time since I did any music theory.
I feel that I've achieved something this evening. Go me.
