The Difference Between a Song and Other Forms of Composition

The song is a vernacular format. It's a form of expression that deals with materials that are familiar to everybody and that are accessible to everybody. The standard pop song has three chords for the most part. And so these are very easy materials to master, so anyone who's interested enough in it can take the trouble to learn those three chords and put together something resembling a pop song. They might not be very good at it, but you can still access the basic fundamental building blocks of the pop song fairly easily.
