A dozen years ago, pianist Shoko Sugitani owned nine pianos, which she kept in different places. She is now down to seven, some of them in Duesseldorf and the rest in Tokyo. She has a favorite piano that she takes with her to important concerts. For the concert scheduled with the Warsaw Philharmonic National Orchestra this month, she has borrowed a made-in-Hamburg Steinway full concert grand piano. It’s the tuning of the instrument that is critical, she explains. She has high, demanding standards, saying, “It is very difficult to find someone who can tune the way I want it.” She relies on Masayuki Matsunaga of Yamaguchi Prefecture to tune the Steinway grand she is borrowing from him, to tune her own Steinway, and all the pianos she uses for her recitals and recordings in Japan.
