Very interesting reading in this tread....
Myself, I'm not any good at this stuff, but I've found a good tool
to help me out when struggling to find where to put the fingers to
make it sound reasonable right.
It is called WinChord and works nice on the PC, even with Win XP.
For those of us who might need a little help, it is downloadable
from my Website at the Progs page. No install needed, just run it
from the folder after unzip. (Only 38 kb)
I don't remeber where I first found it, but I'm pretty sure it is
freeware

Happy playing
