Finding all the music that you need for matins and vespers was really hard for me when I started trying to chant from byzantine notation in Maryland. When I moved back to Pittsburgh I was very fortunate to learn where to find music online. I will share all of the standard sources of music that we use for vespers and matins.
If you go to an Antiochian Orthodox Church you can print the online liturgical guide to find the text for all major services. We usually follow this for our services.
