If you give an informative presentation on instrument families of the modern symphony orchestra, your main ideas will probably be strings, woodwinds, brass, and percussion. The order in which you discuss these instrument groups may not really matter. The pattern you decide on an example of organization.

Topical organization.

Explanation:

As the exercise presents, the pattern chosen to organize is called "topical organization". This is a commonly used format, and works like this: it arranges information according to different sub-topics under a larger one. For example,  following the content of the example, a topical organization would look like this:

Modern symphony orchestra:

          (Information about strings)

   *Woodwinds

           (information about woodwinds)

And so on with the rest of the instruments.
