In tune and top of her game

High-flying soloist Wang Yuja pays as much attention to her instrument as her performance, the perfectionist tells Chen Jie.

Wang Yuja is late to the interview. Before my turn, China Central Television's camera has been waiting outside her dressing room backstage at the National Center for the Performing Arts.

Her mother comes to explain that she was helping to tune the piano because it had not been in good condition at her concert the night before, when she played Rachmaninoff's Piano Concerto No 3 with the London Symphony Orchestra under the baton of Daniel Harding.
