What is difference between master & HEAD?

master is the common name for the default branch. It doesn’t need to exist, but it often does.

HEAD can be thought of as a variable pointing to a specific commit. It can change and isn’t related to a branch.

Issuing new commits changes HEAD, checking anything out changes HEAD.
