Thank you everybody for your posts.

I accept that my wording to question 4 was flawed, and I apologise if I offended anybody.

There are a number of journals and books that discuss the protection of (for sake of argument) traditional music and knowledge. I was advised that mudcat was a suitable site to post on to reach individuals who would hold valuable views and opinions.

Regarding question 4, I was referring to "traditional" music as that which has cultural heritage, and was wanting to compare the extended protection that it should receive to keep it in the public domain against the protection that "commerical" music receives in order to protect its financial income.

I will look into all of your ideas and suggestions in detail.

Thanks again,

Roksana
