At least they didn't compare it to the size of the worlds tiniest violin. :)
On a side note, it's always fun to watch the recommended videos that pop up when the video is done. YouTube has to be doing some geographical tagging in their videos. A bunch of Japanese harmonica videos came up. If you use Google Translate to translate the word harmonica and then cut and paste the results in you pull up an entirely different set of harmonica videos than you would using the English.
The guy who uploaded this vid is a pretty good harp player with a touch of crazy, as all good harp players are. If memory serves me correctly, he once had vid of a jam at a dentist's office and another highlighting the sound made by reedplates drying in front of a hand dryer in a men's wahsroom.
But yeah, Google seems to be geotagging a lot of vids as a matter of course. Your idea could be used to find a lot of hidden gems, Nate: not just Japanese but Persian, Chinese, Hindi... The mind boggles...
I tried every language in Google Translate once. My favorite was Middle Eastern. A young man was playing a guitar in front of a very tall stack of books- high enough to get the top book up to face level (off a table if I remember correctly). He had a harmonica wedged into the pages, sticking out so he could play it. It was the most creative harp rack I've ever seen. :)
