Tatev was born in Armenia to artists Mels Yeghiazaryan and Karine Arsharkyan. She quickly showed a great interest for music and began formal classical lessons in both voice and piano at the age of 6. Until a few years before Tatev's birth, jazz was outlawed by the occupying Soviet Union. Her father's art, secretly collected jazz records, her mom's talent and persistence for continued involvement in the arts were critical for Tatev's development.
Tatev moved to the United States in 2003 after achieving much recognition in the Armenian musical community. Tatev had her first classical solo concert at the age of 9 and thereafter won numerous musical competitions and has appeared on several radio and television shows. After a short time in the States, Tatev became a scholarship graduate of NJPAC's Jazz for Teens program. In 2009 she completed her Bachelor's degree with a full scholarship in jazz studies at William Paterson University.
Tatev is a composer, a production manager/producer and a performer whose current aspirations include composing for films and cartoons, singing, learning, playing, being inspired, hopefully inspiring others and enjoying life.
Most of Tatev's compositions are written for her septet, Soundsketch, to ornate and strengthen the visual experience of motion pictures. Tatev's other ensemble is comprised of her sisters, YYsisters who perform Armenian folk, traditional and classical music in addition to some original music composed by Tatev. Her music is inspired and influenced by classical, jazz and Armenian music as well as her childhood and continues fascination with authentic cartoons, haunting and magical fairy tales: the endless world that imagination is capable of making one experience.
