"Arpi" Ter-Petrosyan possesses what is perhaps the deepest female voice in all of Armenia. She graduated from the State Educational Khachatur Abovyan University in Yerevan. Her astounding vocal range allows for creating what sounds like "bass" parts for the all-female Naghash Ensemble vocalists. A multi-faceted vocalist, Arpine has performed with The Geghard Choir, The National Opera Theater of Armenia, and The Armenian National State Academic Choir. In the past few years, Arpine has gained a remarkable international following as "Arpi Alto."
