This paper presents a small scale study that examined links between the inclusion of nonlinear dynamical processes in musical tools and particular kinds of engagement. Communication-oriented attitudes to engagement that view the tool as a medium for transmission of ideas are contrasted with material-oriented attitudes that focus on the specific sonic properties and behaviours of a given tool, and the latter are linked to the inclusion of nonlinear dynamical elements. Methodological issues are raised and discussed, particularly with regard to the holistic nature of musical instruments, the difficulties of independently testing isolated design elements, and potential methods for addressing these difficulties
