In Warsaw, during the International Fryderyk Chopin Piano Competition, one of the world’s most prestigious piano competitions, another contest, less visible, is underway. Piano tuners representing the leading grand piano manufacturers work day and night, fine-tuning the tone of every note. Each expert has their own philosophy and method of work. It is their intuition that determines how the instrument chosen by the pianist will sound and whether it will become the vehicle of victory. In this contest, emotions and rivalry are no less intense than on stage. Here, the craftsmanship is a form of art.
