Difference between traditional music international music?

Answer 1

Traditional music is the term now used in the terminology of Grammy Awards, for what used to be called "folk music". Full details of this change can be found in the article World music terminology. Other organizations have made similar changes, though in non-academic circles, and on many CD sales websites, the phrase "folk music" is used in a very all-encompassing way.

The International Music Score Library Project (IMSLP), now also known as the Petrucci Music Library after Ottaviano Petrucci, is a project for the creation of a virtual library of public domain music scores, based on the wiki principle. Since its launch on February 16, 2006, more than 33,000 scores, for 16,000 works, by over 2,000 composers have been uploaded, making it the largest public domain music score collections on the web. The project uses MediaWiki software to provide contributors with a familiar interface.
