I’ve just created a site map – there’s a link at the bottom right of every page or you can find it directly at http://abcnotation.com/sitemap.
As you can see, the structure of the site is relatively simple with very few static pages. However, there thousands and thousands of virtual “[tune pages]”, all created dynamically as required. Plus, I guess there are billions of possible “[search results]” pages.
That’s a lot of pages!
