Dear Graham, if someone is needed: I could write about the notation of percussion or vocal music. But I have one problem: I can only write in BSE (bad simple english). I could write it in geman, and someone else, meybee, could translateit. Or I can try writing in english (maybee a good exercise for me), but I need persons helping me with making corrections.
And one last question: In which format do I have to write? I can do it with LaTex, but I'm not experienced with HTML-files.
