There are three main forms of art. The performance arts, the representational arts and the recording arts.
The Performance Arts – Something happening and being shown to a live audience in real time. A few examples of this are dance, music or acting.
The Representational Arts – will always be a tangible object. For example a book, paining or a sculpture.
The Recording Arts – When something has been recorded, such as a piece of music or a scene for a movie. These clips have then been edited and altered for them to be shown to an audience.
