Olga Babasyan moved to Yerevan after graduating from the Tiflis (Tbilisi) Conservatory in the class of L. Truskovsky, V. Wilshau (chamber ensemble), and then — Leningrad, which she graduated as an external student in the class of Leonid Nikolayev.
Like her colleagues, she leaned more towards ensemble performance. She performed in the early years of her life in Yerevan with the teachers of the Yerevan State Conservatory — violinist D. Ledger, cellist Michael Maluntsian, and professor of the Leningrad Conservatory, violinist I.R. Nalbandyan.
Later, in the 1940s, she gave concerts as part of the piano trio at the Radio Committee of Armenia (together with violinist A.S. Khanjyan and cellist Alexander Chaushian). It should be noted that Olga Babasyan devoted a lot of time to educating the students in her class. She played with them, introduced them to four-hand piano arrangements of symphonies and quartets by Joseph Haydn and Wolfgang Amadeus Mozart, and willingly attended concerts with them by major musicians touring in Yerevan at that time.
According to her memoirs, Olga Babasyan treated her students with «warmth, care, and attention even to the most diverse everyday trifles. As Shushanik Apoyan testifies in her book, “the playing of her students was distinguished by the thoughtfulness of the general plan, confident possession of the instrument. Particular attention was paid to work on sound and melodiousness of sound. At the same time, it required movements that free the hand after pressing the finger on the keys, which, in the opinion of modern pedagogy, was redundant, and had no real effect on the already extracted sound. She also carefully worked on technique, starting with scales and ending with various exercises and etudes. It is valuable that Olga Babasyan worked hard on the mobility of the first finger, keeping in mind the special structure that distinguishes it from its «brothers».
Olga Babasyan’s characterization would be incomplete, if not to say that she subsequently invested a lot of effort and energy in organizing the general piano department at the conservatory and skillfully managed its activities.
In addition to Armenian and Russian, she also spoke French. The best students of Olga Babasyan at different times were: pianist-composer Alexander Arutiunian, composer Edvard Mirzoyan, pianists Arpik Azizyan, Marjan Mkhitaryan, Nina Stepanyan, Tereza
Melik-Karamyan, Ashkhen Samvelyan, Roza Tandilyan, and others.
