Let’s start at the very beginning!
When we think about our Armenian Apostolic Church, we think the songs we hear in church are very old. That’s true! But, did you know that the Divine Liturgy (Soorp Badarak) did not have a complete musical publication since the turn of the late 19th century (1800s)?
There are two primary compositions that we use throughout the world. The first by Makar Yekmalian and the second by Komitas Vartaped.
Yekmalian completed his composition of the Divine Liturgy in 1893 and used it within the Cathedral of Tiflis (Now, Tbilisi, Georgia) for two years. In 1895, Catholicos Mgurdich I issued a encyclical to accept this publication for mass utilization within the Armenian Apostolic Church. Whereas, Komitas’ composition was published in Paris, France in 1933.
There are of course further complete publications by Amy Apgar, Khoren Mekhanedjian, and Pietro Bianchini to name a few.
