There was no recorded or productionized music back then. And yet people liked music as much as we do now. So the only way to enjoy music was to do it yourself.
Singing and playing an instrument was just a basic life skill that everyone had back then. (Say, like driving a car or using a computer is today. Not everyone is a professional driver or computer programmer, but not being able to use a computer at all today would mean you failed at life.)
