 It was Raab who introduced her to the technique that made her famous, the 'arm weight' technique of the Russian teacher Theodor Leschetizky, which she had first experienced when seeing Benno Moiseiwitsch perform in Melbourne in the 1920s.It was this which developed the big tone and control that became a feature of her performances of the works of Brahms, Rachmaninoff and Liszt.Raab insisted she not play the piano for a year, so that she could unlearn her previous techniques, and practise with the piano lid down.
