The scope of a site determines what the site is about.
The tag scope is to be used for discussions relating to the scope of Music Fans SE. So, questions about issues such as
- whether a certain question is on-topic, or how a question can be modified/improved to make it on-topic,
- whether an entire topic is (or should be) on-topic or off-topic,
- whether a tag falls within the scope of the site (see also tags)
should all use the tag scope.
