Kivimäki has created accordion trance as her own style of music. It combines the minimalistic tunes and the repetitive rhythm patterns of the kantele harp and the accordion tradition as well as the soundscapes of the contemporary composer and the possibilities brought by music technology. Kivimäki’s distinctive language of music arises from the open-minded use of a Soviet-made Notka accordion and its wistful sound. Additionally, Kivimäki’s strong background in folk music, different instruments like the accordion, the kantele harp and her own voice, and the dancers’ movement and rhythm have an effect on the emergence of music. In addition to concerts, her music can be heard in short films and music videos, on music albums, in dance pieces, in the theatre, in a photographic exhibition with sound, and in a radio drama.
