What qualifies an instrument to be a world instrument? out of the following questions

instruments that are from under developed countries

instruments that are from Africa and Asia

instruments that are outside the classical genre

instruments that are from Canada

The most relevant qualifying factor for an instrument to be considered a world instrument is that it is from Africa and Asia. These regions have a rich history and diverse array of musical traditions that have influenced music globally. Being from under developed countries or outside the classical genre may also contribute to an instrument being considered a world instrument, but it is not as significant as the geographical origin in this context. Being from Canada does not automatically qualify an instrument to be a world instrument, as Canada is not typically considered a focal point of world music traditions.
