Music can effect everyone’s internal peace. I personally experienced a great change in my personality by listening  music. yes it is vary from different persons. Music has various forms like classical, pop, western, hindustani and many. Music is generated by different ways and it has forms like sad, happy, moody etc. Music is not only said to vocal but also with various instruments like veena, violin, mandolin. Every instrument has the better version of that. some specific instruments like mridamgam are made of animals skin.some instruments are played by stings. music has ragas, taalas, laya, jathi etc.
