Olli Saari (b. 1990) is a Finnish organist and composer based in Helsinki.

He holds two master’s degrees in music from Sibelius Academy of The University of Arts Helsinki and has a wide musical expertise ranging from organ improvisation to composition styles. He is an active performer and often collaborates with top choirs in Finland, which include Cantores Minores, Somnium Ensemble and Tapiola Choir.

As a composer, Olli Saari wants to make music accessible to a wider audience without forgetting high artistic goals. A bold sound, melodiousness, counterpoint and historical stylistic knowledge combined with musician’s craftsmanship are important features of his music. Choral music in it’s all forms is very close to his heart and he is currently collaborating with major choral institutions in Finland. In addition to choral music he has composed several major works featuring organ and is one of the most prolific Finnish contemporary organ composers.

Saari’s music has been performed at several music festivals in Finland and abroad – even as far as Japan. His organ works are already gaining foothold in Finnish organists’ standard repertoire, and the first album which features his music was published in June 2023 by American concert organist James D. Hicks. In March 2023 his large-scale work Requiem for choir, soloists and great organ was premiered in the final concert of the Helsinki Organ Festival.
