::Thanks again.  However, if Category:American musicians should only contain sub-categories (see the message there) and as the guidelines referred to above say that people should not be in a parent-category and a sub-category, I disagree with your view that people should be in Category:Venezuelan musicians as well as in their instrument sub-categories.  Do you want to undo your changes, or shall I?  (I am going to bed now - but it can probably wait a bit if you're busy).  Ha sido bueno hablar con usted - gracias y recuerdos (which I hope means "It has been good to talk with you - thanks and best wishes"!)
