Two works that may help you some are:
"Russian Church Singing Vol. 1 Orthodox Worship and Hymnography" by Johann von Gardner, published in paperback in 1980.
"Russian Church Singing Vol. 2 History from the Origins to the Mid-Seventeenth Century" also by Johann von Gardner, published in paperback in 2000.
Both works were translated into English by Vladimir Morosan, and are published by Saint Vladimir's Seminary Press, Crestwood, New York.
One caveat: As in all things Orthodox, no one speaks for everybody or every jurisdiction when it comes to small t traditions.
