This study investigates the compositional and contextual thinking of composer, Stuart Greenbaum, and the preparatory thinking, and teaching experience of pianist, Yvonne Lau, in the preparation of the solo piano work, "First Light". Adopting a practice-informed interview approach with questions drawn from the researcher's own preparation of the work, the study discusses information the composer would like the performer to know and issues the pianist encountered while preparing the work. It also places the findings in relation to seven stages of learning a new piano work identified in the literature (Chaffin & Imreh, 2002; Viney & Blom, 2014). The paper ends with reflections on how both composer and performer intuitively discuss music elements as a whole, emphasizing their connections; how teaching (and being interviewed) offer opportunities for reflection; what can be revealed by different methodologies; the role of score instructions and program notes; and what engaging with new repertoire brings to learning about preparation of a piano work.
