There is no real relation between notation and chords and the language of the
tool it self. Even if I'm running a Dutch version of Rosegarden, when the
document uses chords in a French notation I don't want to change that. At
least not always :-).

In fact, that's where I got the idea.

Because all notes of a chord are described transposing comes for free. Any
major chord is a root, 3rd and a 5th. Creating a C major chord all three note
names are generated and inserted at the correct positions (when needed).
This idea of relative notes opens a lot of interesting options I'm think of
(generating a guitar part based on a leadsheet, generating a leadsheet, ...).
By the way, I use the QString replace for replacing the {x} patterns by the
note name. But maybe I might simplify the code there.
For now I'm just exploring some idea's, the good news, it seems to be not that
difficult!
Best regards,
Niek
