I think this company specializes in piano instruction, but looking at the website, it’s hard to tell. Look at Greg Moffat’s “resume and flowchart.” The HTML code is filled with tables having a single entry, many of them empty. Can’t say I’ve seen them used that way before. This might look like a relic from the early days of the Web, but it’s very recent. The site has been updated many times since 2004, with some interesting results.
