Twenty-one days, 80 participants, 10 finalists. Warsaw’s International Chopin Piano competition, held every five years, has launched the careers of many piano virtuosos. Pianoforte follows seven hopefuls as they progress–or maybe not–through four grueling competition stages. The stakes are high and the pressure is intense–at times too intense for some. From rehearsals to performance, backstage and at home, the camera captures what it takes to make it in this highly competitive world. It’s a case of SPELLBOUND meets TÁR in filmmaker Jakub Piatek’s enthralling documentary. (Greenwich Films) Film Center exclusive.
