Beginning in the mid-1940s, Hovhaness and two artist friends, Hyman Bloom and Hermon di Giovanno, met frequently to discuss spiritual and musical matters. All three had a strong interest in Indian classical music, and brought many well known Indian musicians to Boston to perform. During this period, Hovhaness learned to play the sitar, studying with amateur Indian musicians living in the Boston area. Around 1942, Bloom introduced Hovhaness to Yenovk Der Hagopian, a fine singer of Armenian and Kurdish troubadour songs, whose singing inspired Hovhaness.
