their Indigenous colleagues sat together and enjoyed fascinating exchanges of broken dialogue and gestures.⁴⁸² These were, unfortunately, rare events. Researchers Ian McLean and Greame Skinner both recognise in separate studies concerning the birth of Australian art forms, that the Eurocentric art world of our nation has been slow to realize and interact with the cultural importance of the Australian Indigenous art disciplines of dance, music and visual art.⁴⁸³

So in 2015, this research program is proposing a tertiary education model of interaction that may engender the cross-cultural Indigenous Australian composition to become a staple form of Australian music. The students could be assessed for the level of interaction achieved in the collaboration as well as their abilities to understand conventional practices of the disparate art forms.

Activity theory recognizes two basic processes operating continuously at every level of human activities: internalization and externalization. Internalization is related to reproduction of culture; externalization as creation of new artifacts make possible its transformation. The dialectical relationship between continuity and change, reproduction and transformation, is a challenge to concrete research in local activity system. Today externalization, the transformative construction of new instruments and forms of activity at collective and individual levels has become an equally central theme of research.⁴⁸⁴

The Stuart piano is the new mediating artefact in this model, that has enabled me to reinterpret traditional Aboriginal chants, into new collaborative forms of music. The internalisation is demonstrated by the conventional methods used to categorise the particular sonorities of the Stuart piano sound⁴⁸⁵ , and the conventional notations of the re-compositions. My educations in music practices, my cultural background and musical influences are also my internalisations. The Indigenous collaborators each bring their conventional internalisations of culture, and their musical styles. The collaborative performances of the Yabun Yaguna pieces and our performances of other music at OUR MUSIC demonstrates the externalization. The externalisation is recognised because the conventional internalizations are in a changed form in the collaborative output. The artistic practices of subjects (musicians, composers, performers) are influenced and changed by their active interaction which each other. A new collaborative music is recognised that consists of new materials that have been transformed from their earlier state, a change that is a creative outcome of the collaboration.
