The study summary and design were to assess procedural anxiety and stress in parents and pain perception in children during intradermal testing. Music medicine was incorporated into the study design as a nonpharmacological intervention. Two distinct auditory modalities were used: solfeggio frequencies-174 Hz, 285 Hz, 396 Hz, and 528 Hz-which have been suggested to interact with the human energy field through resonance-based mechanisms, and Turkish classical musical modes (makams), such as Rast, Hicaz, Uşşak, Neva, and Saba, which are modal systems that include microtonal intervals and follow specific melodic progressions that are often associated with different emotional and spiritual effects as well as sensory and emotional regulation potential.
