What is composition?

What is this class about?

To me, composition means spreading information to others that need it in the form of text.  The reason I use the term "text" is because it's not longer by means of pen and paper necessarily, but by email or some form of technology.  I think that most people believe that composition is just essays and books, but it covers so much more than that.  You can be reading instructions on how to install a new dishwasher.  Isn't that technically composition?  It's hard to answer this question because people have different connotations of words.  This might be because of the different types of composition that they have read.  In today's world there is no way to go about your business by speaking to everybody you meet face to face, although direct confrontation is important.  I think it has changed drastically in the past 60 or 70 years.  Composition changes daily.  Enough said.
