This thesis examines maple sugaring as an artistic, relational, and ecological practice through the development of Singing Sap, a participatory, site-based art project conducted over three years in Ithaca, New York. Drawing on social practice, material inquiry, posthumanist thought, and Indigenous understandings of reciprocity, the project explores how humans might cultivate more ethical and attentive relationships with the more-than-human world. Organized into three sections, Searching, What Can I Give?, and Singing, the thesis traces a movement from a desire for connection, through the challenges of reciprocal engagement, toward a practice of listening and gratitude. Maple sugaring functions simultaneously as material process, participatory framework, historical inquiry, and interspecies collaboration. Through public programs, collective labor, sound-based experimentation, and gallery installations, the research investigates how ecological relationships can be experienced rather than merely represented. Reflecting on the tensions among settler-colonial histories, extraction, artistic authorship, and social practice, the thesis argues for reciprocity as an embodied practice rather than an abstract concept. Ultimately, Singing Sap proposes that art can create conditions for attentiveness, care, and relationality, offering maple sugaring as a model for reimagining human participation within broader ecological communities.
