That's fine, but I think you have missed one part ogf Guy's question. Is it 
possible to pass a parameter
to the startBarre macro/function ? Because the text must be variable. It's 
a C followed by roman numerals of the fret (I to XII or more)
It would be nice to state \startBarre{VII} or something similar. Other way 
would be to define 12 or more functions :-(
