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 summer courses at Salzburg Mozarteum with Tatiana Nikolaeva, a pupil of the great Russian pedagogue Goldenweiser, and with French pianist Germaine Mounier. She took part in various other masterclasses of pianists/pedagogues as Peter Feuchtwanger, Edith Picht-Axenfeld, Elza Kolodin, Aldo Ciccolini, Jan Wijn, Roberto Szidon.
In London she studied chamber music with Yonty Solomon at the Royal College of Music and in New York entered professional studies at MSM 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 to facilitate 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.
Tamara has been involved in chamber music, pianoduo, accompanying and in an interdisciplinary collective with dancer/choreographer Erik van Duijvenbode and designer Willemijn Schellekens. She appeared in multiple piano performances with pianists such as Jeroen van Veen, Jeroen Riemsdijk, Irene Russo, Sandra Mol, Mike del Ferro and Fred Oldenburg.
Besides the traditional pianorecital, Tamara has been developing other performances such as lecture-recitals, programmes with minimal-music, transcriptions and performances in public space. She made various recordings for radio and television and as a soloist recorded for Briljant Classics and Emergo Records with various musical styles, including Dutch composers Simeon ten Holt and Chiel Meijering, and composers Antonio Soler, Haydn, Schubert, Chopin, Rachmaninoff, Scriabin, Debussy, Ravel.
In 2011 she initiated Foundation Concerts2Connect to link artistic and engaged projects, for example by organizing charity concerts and activities and performances for those who cannot attend performances easily, like in hospitals.
