Arvo Pärt, the Estonian classical and sacred music composer, is widely celebrated for his development of the tintinnabuli compositional style and his status as one of the most performed contemporary composers globally. He is also noted for adopting the practices of minimalism.

Pärt was born on September 11, 1935, in Paide, Estonia. His early musical explorations involved experimenting with his family's broken piano. His formal musical education commenced in 1954 at the Tallinn Music Secondary School. However, he took a break from his studies from 1954 to 1957 to fulfill his military service. Pärt resumed his studies at the Tallinn Conservatory in 1957, where he studied composition under Professor Heino Eller. He later secured a position as a recording engineer at a local Estonian radio station. Pärt's early published works were composed for film and theater. In 1962, he achieved recognition by winning the All-Union Young Composer's Competition for his compositions "Our Garden" and "Stride of the World."

He completed his studies at the Tallinn Conservatory in 1963, initially adopting a neo-classical style of composition and later transitioning to the renowned twelve-tone style of Arnold Schoenberg. However, he faced creative difficulties and sought further studies, delving into Gregorian chant, polyphony, and classical Western music. These studies led to some of Pärt's most well-known compositions from the 1970s, including "Tabula Rasa," "Spiegel im Speigel," and "Fratres." Music critics appreciated the distinctive style of these works, which Pärt described as tintinnabuli, evoking "the ringing of bells." His compositions often featured sacred texts, with notable pieces such as "St. John Passion," "Te Deum," "Litany," "Magnificat," and "The Beatitudes."

Pärt's music soon captured the attention of Western audiences, largely due to Manfred Eicher, who recorded many of Pärt's compositions for ECM Records. His music has been performed at renowned events, including the Rheingau Music Festival, by the Windsbach Boys Choir, and with the Bavaria Radio Symphony Orchestra, as well as by the Hilliard Ensemble. Pärt dedicated musical performances to notable figures, such as "Für Lennart," a tribute to the late Estonian President Lennart Meri, and other compositions honoring the late Russian investigative journalist Anna Politkovskaya, whom he admired for bringing attention to the victims of abuse in Russia.

Currently, Arvo Pärt is in a collaboration with the Pontifical Council for Culture under Pope Benedict XVI's leadership, a position he has held since 2011. In 2008, he released his Symphony No. 4, the first symphony since 1971, which received a Grammy nomination for Best Classical Contemporary Composition. In 2014, he won the Grammy Award for Best Choral Performance for "Adam's Lament." Additionally, he was honored with the prestigious Praemium Imperiale award from the Imperial family of Japan for his outstanding contributions to choral works and sacred music.
