Old age is not a disease, which is an inescapable reality of the human existence on the planet earth, plays a crucial role in the global demographic transition. Failure to adaptations of the ageing which can lead to frustration, bitterness, hopelessness, helplessness and insecurity makes older people liable to get depression in later life. The objectives of the study were to identify the socio demographic variables of aging women, to assess the pre-test level of depression beforeintervention, to evaluate the post-test level of depression after the therapy intervention, to determine the effectiveness of music therapy intervention and to find association between post test scores in reduction of depression with the selected demographic variables. Quantitative evaluativeresearch approachwith one group pretest and posttest, pre-experimental design was adopted in this study. Non probability purposive sampling technique was used to select the 60 samples. The music therapy was administered for a period of four weeks among aging women who were selected based on the inclusion criteria. The level of depression was assessed using geriatric depression scale.The finding of the study shows that the pretest score was 34.47 with standard deviation of ±2.93. The posttests score was 21.37 with standard deviation of ±1.95. This study revealed that music therapy was effective and healed the depression among aging women. So the differences are large and it showed statistically significant difference (P ≤ 0.001) in paired test. There is significant difference between pretest and posttest level of depression amidaging women at level of p<0.05. So, hypothesis have been accepted. Hence the objectives have been achieved and hypothesis is proved.
