Tatyos Eñserciyan or Tatyos Efendi, was a famous composer of classical Turkish music, and his works continue to be among the best-remembered and often played pieces of the genre. An Armenian from Istanbul, Tatyos Efendi was born in 1858 in the Ortaköy district of Istanbul as the son of Monakyan (Manuti), a musician at the Ortaköy Armenian Church. Tatyos Efendi's family had a minor trading business and when he finished the Ortaköy Armenian Elementary School, he started an apprenticeship at a locksmith and later became an apprentice at a savat workshop (a traditional form of silver work). Due to his deep interest in music, Tatyos Efendi left his apprenticeship and bought a second hand kanun to receive his first music lessons from his uncle Movzes Papazyan. He played the kanun with amateur groups and musical meetings in a family setting. Later, he took violin lessons from Kemani Kör Sebuh and lessons in singing and theory from Andon and Civan brothers and singer Asdik Aga. He conducted many fasıl concerts in various places including the Pirincci Gazino with artists like Karakaş, Ovakim and Şemsi. He composed many popular songs and instrumental works for fasıl.
