You've got to be kidding me. It means it's a painting, not an actual pipe. And by extension, other representational art is not what it represents but something else. But it doesn't matter to you, because the painting is not being performed by a human, and is the same every time you look at it, therefore it, you claim, it doesn't have a soul.
A painting exists to moment it is drawn and it is persistent more or less for at least a few hundred years.
Music on the other hand is ordered vibration of air molecules (and this is something different than a composition, hence the pipe example). These vibrations are vanishing immediately.
Therefore a painting does not have to be performed like music.
Every form of human art has a soul, a painting, or the actually played music.
Computer made "art" does not have a soul, although it may have the same physical structure than a human made one.
