Category sort for keys?

[steltz]

This page:

http://imslp.org/wiki/Violin_Concerto_N ... ps,_Henri)

had bracket issues that were causing the page to mess up toward the bottom. I found this:

Key={{Key|a||

which looks like a category sort. So I changed it to

Key=[[Key|a]]

Now it appears correctly and the rest of the page displays properly, but the "a" for the key is in red, which means the page doesn't exist.

Do we even have a category sort for keys? Should I just remove it and put in "A minor"?

I designed a template to categorise the commonly accepted major and minor keys - up to seven sharps and flats. So the {{Key|<designation>}} template takes care of formatting and categorising; if you only want formatting use {{K|<designation>}}.

Format: major uses capitals, minor uses lower case; b indicates a flat, # a sharp.
