The comparison of mean, standard deviation, mean difference, t-value, and ’p’ were used to assess the value of post level of blood pressure in the experimental group .The pre – test blood pressure and post test blood pressure which clearly reveals the effectiveness of music therapy in reducing the blood pressure. Demographic variables of the school teacher like history of hypertension with relationship is statistically associated with stages of hypertension at p value <0.05.Conclusion: The study findings will enable the nurses to plan and implement health education programme regarding the prevention of hypertension and its various treatment modalities in future.
