Tamara Rumiantsev studied at Utrecht School of the Arts with Norwegian pianist Håkon Austbø where she obtained her Piano Performance degree. She graduated summa cum laude and went on for masterclasses at Mozarteum Salzburg with Tatiana Nikolaeva, a pupil of the great Russian pedagogue Goldenweiser, and with French pianist Germaine Mounier. Earlier she took part in masterclasses of Peter Feuchtwanger, whose principles on piano technique fascinated her.
In London she studied at Royal College of Music with Yonty Solomon and in New York with Nina Svetlanova (herself a pupil of Heinrich Neuhaus) and the Russian-American pianist Bella Davidovich. Scholarships from The British Council, VSB-fonds and Prins Bernhard Fonds allowed her these years of study. In the US she was a finalist in the St. Charles World Piano Competition (1995), after which she made her debut with the Schumann Concerto. Back in The Netherlands she graduated both in Musicology and Music Theory at University of Utrecht and Utrecht School of the Arts.
In 2002 she made her debut in the Concertgebouw (Kleine Zaal) with chamber music and solorepertoire. In 2004 she performed both Concertos by Ravel with the Noord Nederlands Orkest, conducted by Jacques Mercier.
