Considered one of the master Hungarian string players, this artist relocated to England where she has been an influential instructor at the Royal College of Music in London as well as the Purcell School of Music and the Guildhall School of Music. She has a particular talent working with young people, especially those gifted with remarkable talent at an early age. Rozsa, whose name appears with great frequency with the "z" and "s" reversed, was a great encouragement and inspiration to the young violinist Jocelyn Montgomery, who combined studies with Rozsa and busking in the streets of London and went on to record an important album of the music of Hildegard van Bingen. Another of her students, Jocelyn West, began playing at the age of six.
Rozsa was a member of the Bath Festival Orchestra at a time when the ranks of that ensemble were loaded with virtuosos, including the then-16-year-old cellist Jacqueline du Pre. Rozsa is married to the cellist Martin Lovett, a member of the Amadeus Quartet.
