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.
