Q:

What do you call the first string of characters inside an HTML tag?

This is an element: <p class="blah">Hi World!</p>
This is a tag: <p class="blah">
But what is the proper technical name for the p inside the tag?
Asking for a friend. :)

A:

It’s the tag name. From 8.1.2.1:

The next few characters of a start tag must be the element's tag name.
