This group's goal is to exchange information about pre-1700 Middle Eastern music.
"Middle Eastern" is intended to be a very broad area, including Arabic, Turkish, and Persian music, and music which was (possibly) influenced by Middle Eastern music, such as the Cantigas de Santa Maria of 13th century Spain [ wikipedia ].
We're most interested in pre-1600 CE music, but since these early sources are so rare, we've set the cutoff to 1700 CE. That includes authors such as Ali Ufki (1650) and Prince Katemir (late 17th century).
Because this stuff is fascinating!
