Jarkko Hartikainen explores sound phenomena in his music, including the ‘musicalisation’ of speech, i.e. how the harmony of music can imitate speech. He says that he “believes in mankind’s everlasting curiosity towards the new, and in the power of innovation to radiate across different human activities”. Having studied with Paavo Heininen, he studied further abroad and names Helmut Lachenmann as his principal influence. He has rapidly gained international recognition with his works, and he has received commissions from leading ensembles such as the Ensemble Schwerpunkt brass quintet. He also writes about music and holds a number of elected posts in various associations.
