Bánk Sáry composed his choral work Blue Sky for female voices commissioned by the town of Debrecen for the Béla Bartók 26th International Choir Competition in 2014. The composer says about his work: "I have used extracts of poems in Miklós Zrínyi's manuscript The Valiant Lieutenant. The choir sings the initial sentence in Latin in unison, then the music gradually becomes polyphonic before a playful, rhythmical passage takes its place in the middle of the piece. At the end of the almost five minute movement the beautiful text is sung by the choir in a homophonic chord progression."
