Haslbeck F. Music Therapy with preterm infants – Theoretical approach and first practical experience. Music Therapy Today, 2004;5(4): 1-16.
This thesis discusses the impact of music therapy for preemies and why they need it due to the continuous over-stimulation they receive in NICU. The environment causes stress, disturbs sleep and rest periods so that preemies lack proper sleep-wake rhythm.

Haslbeck F. Research strategies to achieve a deeper understanding of active music therapy in neonatal care. Music and Medicine. 2012; 4(4): 205–214.
This article proposes a flexible methodology that achieves a deep understanding of the therapeutic process of active music therapy in premature infants and their parents.

Hui-Ling Lai HL, Chen C, Peng J. T. C., Chang, F. M., Hsiao, Y. H, Chang, C. Randomized controlled trial of music during kangaroo care on maternal state anxiety and preterm infants’ responses. International Journal of Nursing Studies. 2006; 43(2): 139–146.
Infants in the music therapy treatment group in this study experienced more quiet sleep states and less crying. Music during kangaroo care also resulted in significantly lower maternal anxiety in the treatment group. Authors conclude there is evidence for the use of music during kangaroo care as an empirically-based intervention.
