It is backed by science that music has a therapeutic effect on us. That is the reason in the past our princely states had music maestros. From Baiju Bawra to Tansen, the list is uncountable.
Even Vedas had a separate book dedicated to music Samaveda. In Hindustani classical music, we have many ragas which fit on a particular occasion, mood, season and time of the day.
Western musicians were not behind either: Mozart, Bach, Beethoven are celebrated ones.
I find it mind-boggling. One lifetime is not enough for learning and understanding the same.
