Very preterm infants are at a high risk for language delays that can persist throughout their lifetime. The auditory system is rapidly developing and highly sensitive to acoustic stimulation during the third trimester of pregnancy. The acoustic nature of the womb provides the essential foundation for auditory perceptual skills necessary for language acquisition. In contrast, the NICU environment presents a wider spectrum of sounds that can alter the early development of the auditory system and cause delays in language acquisition. Research supports the importance of early exposure to speech sounds for optimal development of auditory perceptual ability and the critical role of the intrauterine characteristics of language. Pitches below 300 Hz, as well as rhythmic patterns and prosodic contours are highly salient intrauterine features of language that make up the infant’s initial auditory experience. The purpose of this study is to form a theoretical framework as a structure for understanding how intrauterine speech characteristics of pitch, rhythm, and prosody can be implemented as active ingredients in a music intervention to improve auditory development and long-term language outcomes in very premature infants. The framework is presented and described in detail. Implications for a future research agenda and applications for clinical practice are explored.
