The Library of Congress' Performing Arts Encyclopedia features a large collection on Coptic Chants, one of the oldest liturgical chants performed today. Visitors unfamiliar with the Copts of Egypt, and their music, should peruse the "Introduction" for an excellent few paragraphs about them. Going back to the menu of Galleries at the top of the homepage, visitors will find the "Music Recordings" link, where they can listen to MP3s of the recordings or they can listen to them on RealMedia. Choose "View Music Recordings Gallery", and then from there choose any of a number of CDs containing the chants, including holiday selections and those for special services. A gallery of photographs is available via the "Photographs" link, and can be viewed by topic, or as a whole. There are also several "Videos" for visitors to watch here, including the 100th birthday party for the Institute of Coptic Studies' ethnomusicologist Ragheb Moftah, as well as his funeral.
