Music Therapy During Hypothermia in the NICU

This study will use live, improvised, entrainment-based music. The music will be applied to synchronize with the newborns' breathing patterns, adapting the tempo to the breathing rate, with characteristics that seek to induce a state of relaxation in the patient: moderate volume (below 65 dB; this measure will be validated using the ambient noise indicator of the neonatal intensive care unit), simple harmonic sequences (tonic-subdominant-dominant), melodies that avoid large intervals (beyond a third), medium registers, and a stable pulse. Once the music therapist synchronizes the pulse of the music with the newborn's breathing, the music will be gradually become slower (approximately 10-15%), the volume will be adjusted, and the complexity of the music will be reduced until the patient can transition to a state of greater relaxation. The music therapy session will last 10 minutes, after which the music therapist will leave the room.
