The dialogical notion of vertical polyphony, referring to multiple internal voices, is explored in relation to clinicians’ professional and personal selves. We describe an experiential training exercise developed to enhance clinicians’ awareness and understanding of their inner dialogue, and create space to practice what Schön terms ‘reflecting‐in‐action’ and ‘knowing‐in‐action.’ The exercise involves stages of personal reflection, discussion in groups of two or three, and shared learning by the group. A number of variations of the exercise are described. The invited commentaries following the article provide a sense of participants’ reactions to the exercises. Readers are invited to adapt the exercise to suit their own setting and to enhance reflective practice.
