This session explores the question: “What is tacit knowledge in music therapy with parent child dyads, and how can we make this knowledge ‘knowable’ to others?” Tacit knowledge is both difficult to describe and challenging to convert into shared knowledge, but it is necessary. Tacit knowledge is made up of, in part, personal knowledge. Music therapists’ personal knowledge is informed by a temporal-aesthetic way of knowing our craft that seems to defy explication. Communicating tacit knowledge is a process that is both fraught with epistemological differences of opinion and necessary for furthering a general theory of music therapy.
