Violinist by profession, the Japanese-born Viennese musician Tomoko Mayeda also learned to play the piano from the age of four. Her teacher and mentor Paul Badura-Skoda often took the time to teach her at the piano in addition to his support as a pianistic accompanist at countless concerts and a joint CD recording. Mayeda had for a long time cherished the wish of being able to accompany herself at the piano, which she was finally able to realise during the pandemic through technical refinements: first, Mayeda recorded the piano part, to which the violin was then recorded in a second recording session. Since the otherwise usual and necessary agreements regarding musical features are omitted, the result is Tomoko Mayeda “100%”, an uncompromising interpretation of W. A. Mozart’s late Viennese violin sonatas (B flat major, K454; E flat major, K481; A major, K526).
