Do rules define how good you are?

In those days, music was discovered, instruments were invented and playing
was standardized. The grammar of each music form was defined and was taught down through the generations. The expectation from a musician was to follow the grammar rules and improvise within the framework. With the advent of light music, rules were broken. It created infinite possibilities of mixing different music forms. Advancements in technology aided by introducing new sounds. But have all the combinations been utilized? Is the majority of the light music industry settling into one discovered path and not exploring new options? Can the new generation pick up these possibilities and will they be recognized? Has society realized this?

I am not suggesting however that a person can right away start creating/performing music without knowing some forms at least to some detail. It is necessary to know what exists to create something else. Also, the rules of classical music preserve our tradition and uniqueness. I am talking about bringing out this uniqueness in a different way.

Even in light music, singing and playing started having unwritten rules/notions - for example the rules of olden days were having a carnatic base and a high pitch voice. As times changed we got newer voices and different styles of singing in, but the majority expectations made all the singers sound alike with a specific set of criteria. I feel the general notion around an ideal singer is curbing natural voices and expressions. Why should everyone follow this notion laid down by a few to be a good singer? There are a few exceptions to this who have made it big - I feel the exception should become the majority and vice-verse.

There are a lot of debatable opinions above. The point I am trying to make is that the younger generation need not always stick to well trodden paths and society should drop its general notions and accept people naturally.
