This presentation explores the role of dyadic (parent-child) music therapy in enhancing parental perceptions and mentalization processes. Sixteen parent-child dyads (children aged 4–6) participated in the study. The intervention group (n=8) engaged in 12 sessions of dyadic music therapy, while the control group (n=8) received no therapeutic intervention during the same period. Parental representations were assessed pre- and post-intervention using the Five-Minute Speech Sample (FMSS, Sher-Censor, 2015). Anticipated results suggest that parents in the intervention group will show greater reflective functioning, warmer, more empathic narratives and increased sensitivity toward their child’s inner world, compared to the control group. Framed by attachment theory, relational psychoanalysis, mentalization and communicative musicality, this study highlights how shared musical experiences can strengthen parent-child relationships and support reflective parenting. The presentation will discuss clinical implications for international music therapists working with families in diverse cultural contexts.
