The order was set after Polish Culture Minister Marta Cienkowska drew the letter "T" during a press conference on Tuesday.
She said the event holds special significance this year as it launches centenary celebrations of the competition, first held in 1927.
In 2027, a wide range of events will be held to mark 100 years since Warsaw hosted the first Chopin Competition.
The jubilee will culminate with the 20th edition in 2030.
Cienkowska described the competition as one of the world’s leading cultural events and a symbol of Polish identity.
“It was here in Warsaw that many pianists skyrocketed to international careers, becoming ambassadors of Chopin and Poland on all continents,” she said.
Eighty-four pianists from 19 countries will compete, including 28 from China, 13 from Japan and 13 from Poland.
The Polish entrants are Piotr Alexewicz, Michał Basista, Mateusz Dubiel, Adam Kałduński, Antoni Kłeczek, Mateusz Krzyżowski, Viet Trung Nguyen, Piotr Pawlak, Yehuda Prokopowicz, Zuzanna Sejbuk, Jan Widlarz, Andrzej Wierciński and Krzysztof Wierciński.
Polish President Karol Nawrocki sent a letter to participants praising their artistry and recalling past winners such as Halina Czerny-Stefańska, Adam Harasiewicz, Maurizio Pollini and Martha Argerich.
The prizewinners will be announced on October 20. The first-place winner will receive EUR 60,000 along with concert engagements and recording opportunities.
The first stage will be preceded by a gala concert on Thursday featuring four past winners.
Yulianna Avdeeva, the 2010 winner, and Garrick Ohlsson, the 1970 winner, will perform Francis Poulenc’s Concerto for Two Pianos and Orchestra.
Bruce Liu, who won in 2021, will be the soloist in Camille Saint-Saëns’ Piano Concerto No. 5 in F major.
All three will then be joined by Dang Thai Son, the 1980 winner, for Johann Sebastian Bach’s Concerto for Four Pianos.
The gala will open with the Warsaw Philharmonic Orchestra under Andrzej Boreyko performing Chopin’s Polonaise in A major in an orchestral arrangement.
