Music therapy could reduce stress and the stress response. The aim of this study was to investigate the role of music therapy in alleviating stress during day surgery.
Sixty patients undergoing day surgery were randomized to one of three groups, each containing 20 patients. Before and during surgery, patients in group 1 listened to new age music and those in group 2 listened to a choice of music from one of four styles. Patients in group 3 (control group) heard the normal sounds of the operating theatre. Plasma levels of cortisol and subpopulations of lymphocytes were evaluated before, during and after operation.
Plasma cortisol levels decreased during operation in both groups of patients who listened to music, but increased in the control group. Postoperative cortisol levels were significantly higher in group 1 than in group 2 (mean(s.d.) 14.21(6.96) versus 8.63(2.72) ng/dl respectively; P < 0.050). Levels of natural killer lymphocytes decreased during surgery in groups 1 and 2, but increased in controls. Intraoperative levels of natural killer cells were significantly lower in group 1 than in group 3 (mean(s.d.) 212.2(89.3) versus 329.1(167.8) cells/microl; P < 0.050).
Perioperative music therapy changed the neurohormonal and immune stress response to day surgery, especially when the type of music was selected by the patient.

- "Music has been found to reduce stress, the effects demonstrated through reduced cortisol levels, and affect immune system strength, as measured by salivary immunoglobulin A. There is now a large body of evidence highlighting the positive effect of music in a variety of clinical settings such as dental care, palliative care, paediatrics, surgery and anaesthesia678. Potential health benefits can also apply outside of a clinical or laboratory setting, and can extend to enhancement of general feelings of subjective health and wellbeing – more specifically psychological factors such as stress, anxiety and depression. An important and growing area of this research is concerned with the effect of music listening on pain relief. "

Klassik, Pop, Country und Tanzmusik bei Leardi et al., 2007) auswählen konnten, was jedoch keinesfalls als repräsentativer Ansatz diesbezüglich gewertet werden kann. "

- "It is longestablished that the right hemisphere is specialized for processing the emotional information conveyed through music (Adolphs & Tranel, 1998). Listening to music can have a tremendous effect on our minds and bodies (Khalfa et al., 2003; Leardi et al., 2007). "

ABSTRACT: Introduction: Music means the act of coloring the mind or emotions of an individual with the emotion of raga. Keeping in view the limited research on effects of music training, on emotional development, the present study was planned to find out the effect of music training on depicting emotions conveyed through Ragas.
Method: A set of tones (Pakad) of seven Ragas sung by a professional singer were recorded. Recording was done in quiet environment with fixed speaker to mic distance. 20 Trained (group I) listeners and 20 (Group II) untrained listeners participated in the study. Participants (group I) were trained for one hour each every day for a week by trained professional. All the participants carried out perceptual analysis to identify different emotions depicted by the different ragas. The comparison was done to see which group was better in identifying the emotions.
Result: The results indicated that individuals who had music training could identify the emotions through ragas better than that of individuals who do not have music training. Anger, happiness and devotion were the most accurately identified emotions by both the groups.
Implications: The study implies that music training definitely is capable of improvising suprasegmental aspects to understand the underlining emotions in speech. The results of the study highlight the importance of combinations of different musical tones to highlight the superimposed emotions in speech.
