You just put a heading and two paragraphs into the page and they appeared in the browser.  The head section of the code is for less visible stuff.  The first thing to put in is the title of the page.  A title is not a heading it is special.

Put a new blank line between the two head tags in your code.  On that line put:

<title>My Music</title>

Save it but before you refresh the browser look at what text appears in the tab of the browser for the page.  Then refresh and you should see that change.
