[9] Born in Adapazarı, declared blind four days after his birth, Hrant as a child sang in the choir of an Armenian Apostolic Church.
In 1918 the family returned west, first to Adapazarı and then to Istanbul, where Hrant continued his musical studies under some of the leading teachers of the time, including Kemani Agopos Ayvazyan, Dikran Katsakhian, and Udi Krikor Berberian (all of whom were Armenians).
Some of his Turkish recordings were released internationally as early as the 1930s, first on RCA Victor, and later on such labels as Balkan (New York), Perfectaphone and Yildiz (probably, according to Hagopian, a single company, address unknown), and Istanbul (Los Angeles).
Composer Şeirf Içli introduced him to Kanuni Ismail Şençalar, in whose group he played for a while, leading to opportunities to perform on Ankara Radio.
The trip, however, led to a series of concerts in New York City, Boston, Detroit, Los Angeles, and Fresno, California, playing both Turkish classical music and his own compositions.
This tour apparently increased his prestige at home: he began to perform frequently on Istanbul Radio, first as a soloist and later with a chorus he formed.
[9] He toured internationally again in 1963, playing in Paris, Beirut, Greece, the United States, and Yerevan, then the capital of the Armenian Soviet Socialist Republic.
