In the world of art there are generally four steps:
The artist comes up with an idea. That idea is then manifest in some outwardly physical (and possibly) repeatable form. Then that is put out in the world in some way.
The Creation part is as easy to understand as it is difficult to do.
The Production part can take various forms. For example, for a piece of music this might be writing it down in musical notation or recording it on some form of media, whether tape (that can be used to create things like albums) or as a digital file.
Then there is the Distribution. Certainly an artist who is only interested in the Creation part might not even go to the Production step, simply having the music in her head or performing it in the world yet not capturing it so that the performance is ephemeral. But she might want to create artifacts for her own use or edification. In this case, the work of art doesn’t go out into the wider world but it still exists in a form that someone else could have it. (E.g., If Renée Fleming sings in her shower, no matter how wonderful it is, it only exists in that period of time. If she records herself singing in the shower, then that performance exists after the time of the performance.)
In the case of something that has been created and transformed into some sort of artifactual being, there is the possibility for the Acquisition by others: Someone buys the painting or downloads the music.
While this is a linear model that leads from the creator to the object and vice versa, there are situations where there is a disruption because it very well may be the creator is not the person who is thought to be the person who has created the work in question.
