A method for treating depression is disclosed. By allowing patients suffering from depression to hear jinyangjo-jangdan (a very slow rhythm) of sanjo (a style of traditional Korean music), the method can be useful in replacing medicinal treatment since the method has an excellent therapeutic effect with a level similar to that when a drug is administered even without administering any drugs, by promoting the activities of monoamine compounds such as serotonin and a brain-derived neurotrophic factor (BDNF) in the brains of patients suffering from depression.
