For the initial sound experiments with trees, we used our hands to touch the trees in various ways in order to create sound from this interspecies contact. However, we thought that integrating materials from the land around the trees, as touch interfaces, may be an idea worth exploring and offer more nuanced interspecies sounds. For this research stage, we explored land-based practices and indigenous ways of knowing, led by Lara Felsing, artist and ECU grad student. Lara developed a set of ‘tree feelers’ based on drum mallets, rutes, and brushes and bows for string instruments, handmade with local plant-based materials. The tree feelers help us listen to the sounds of trees, and the material character of the plant life participating in the project.
