Ayrapetyan was born in 1984 in Yerevan, Armenia.
It was during his studies at the Moscow Conservatory that Ayrapetyan began to immerse himself in Armenian piano heritage, paying special attention to rarely performed works by Armenian composers – the research and study of which remains paramount to his career as a pianist.
This period was the start of his extensive concert activity in which he performs works by Tigranian, Chukhadjian, Komitas, Melikian, Spendiarian, Barkhudarian, Stepanian, Khachaturian, Babajanian, Arutyunian, Abrahamian, Bagdasarian, Avetisian, Mirzoyan, Amirkhanian and many other Armenian composers, which eventually led him to produce his own concerts.
After completing his studies at the Moscow Conservatory, Ayrapetyan performed widely in many countries, receiving an enthusiastic response from critics and audiences alike. He was awarded the State Prize of the Republic of Armenia for his outstanding contribution to the development and popularisation of Armenian classical music.
