Erkki Kurenniemi

At the suggestion of musicology students Erkki Salmenhaara, Ilkka Oramo and Ilpo Saunio, Professor Erik Tawaststjerna invited Kurenniemi to design an electronic music studio for the university.

For instance, Dimi-O (1971) is based on an optical interface, the original purpose of which was to read sheet music graphically.

Dimi-O was also used in tandem with a dancer, whose movements were transformed into music (see Section 2.2 Film, media and video works).

Part of Kurenniemi's compositions are realized in a collaboration - e.g. "Saharan Uni I & II" (1967) with Kari Hakala and "Inventio/Outventio" (1970) and "Mix Master Universe" (1973) with Jukka Ruohomäki.

Many of the Kurenniemi's pieces are first realized as an equipment testing - e.g. "Andropoidien Tanssi" (with Andromatic), "Improvisaatio" (with DICO) and "Inventio/Outventio" (with DIMI-A).

The films were shot in 1964–1971, but their exact completion dates are difficult to determine, as Kurenniemi only showed his work to a few friends at his home.

From the early 1980s onward he kept a constant video and photograph log of his surroundings and personal events, with the aim of producing material for a digital virtual world, to be compiled some time after his death, in which his life would be the central element.

[citation needed] All of Kurenniemi's films and the Dimi-S instrument as well as Master Chaynjis, an early robot from 1982, are today in the collections of the Finnish National Gallery (FNG), the Museum of Contemporary Art Kiasma.

Parts of these private and public archives and artist projects were shown also in a solo show at Kiasma Museum of Contemporary Art in Helsinki from 2013 to 2014.

Harmonies are symmetrical, that is, their interval relations remain constant regardless of whether the divisor set is read from beginning to end or vice versa.

In Kurenniemi's theory, both major and minor chords generate the same harmony, which in his view would explain their equal status in Western tonal music.

Around the start of the 1990s, he wrote yet as unpublished articles concerning a theoretical concept on trivalent networks which he called the Graph Field Theory on space, time and matter.
