The Solemnity of the Nativity of John the Baptist

Unfortunately, I don't have time to do the lengthy post I'd like to do for this major solemnity, and I already know that I will not have any time to blog tomorrow at all. I will just link to this page, which has some background on the solemnity, as well as this page, which contains the text of the traditional Latin hymn sung on this day, "Ut queant laxis." And this page will tell you the importance this particular hymn had in terms of the development of the musical scale that we use.
