Considering the variety of interests Sonja Kalajić has, we can freely say that this is one true 21st Century Renaissance artist! Violin is her main instrument (which she graduated at the Faculty of Musical Arts in Belgrade, class of prof. Dejan Mihailović), and she is the first and only professional saw player in Serbia! She learned to play this unusual instrument from one of the greatest Argentina experts – Rodrigo Gera. But there is more – in 2011 she perfects playing castanets with famous Inma Gonzalez in Barcelona with whom she performs. She also plays a mandoline.

Sonja was the first Serbian violinist attending specialization in the domain of interpretation and arrangement of Tango music in Buenos Aires with the most prestigious experts - Fernando Rodriguez and Enrique Postma. She founded numerous chamber ensembles (Duo Seme, Duo Maska, Quintecho, Trio Singidunum, and the present Sensartika trio) for which she arranged music. Besides working as an arranger, she is also a composer – she composed for TV shows, radio dramas, as well as other chamber ensembles and orchestras. The famous violinist Nemanja Radulovic, elected Sonja's composition "Vatra suze" (The fire of tears) on his album "Journey East" published by Deutsche Grammophon. Finally, she appeared as an actress in theater and film for what she received rave reviews!

She recorded two CD's (with Sensartika, a quartet): "How to listen to a concert" (with different subtitles: "History of dance – from the Middle Ages to boogie- woogie" and "the ball of a romantic world") and "Saw friendly". The third CD "Fauna Sacra" (Metropolis Music, 2019) continues to present unique and noble artistic ideas of Sensartika trio - along with Sonja there is Darko Armenski (clarinet, saxophone, kaval, bagpipes, djembe ) and Miloš Marić (guitarist).
