They told me they were headed for a planet the name of which I had not heard before, and they talked among themselves, gaily and happily, but in such a way that I did not seem to be left out. From their talk I gained the fact that some form of art was being presented at the festival on this planet. The art form was not alone of music or painting, but was composed of sound and color and emotion and form and other qualities for which there seem to be no words in the language of the Earth, and which I do not entirely recognize, only gaining the very faintest inkling of what they were talking of in this particular regard. I gained the impression of a three-dimensional symphony, although this is not entirely the right expression, which had been composed, not by a single being, but by a team of beings. They talked of the art form enthusiastically and I seemed to understand that it would last for not only several hours, but for days, and that it was an experience rather than a listening or seeing and that the spectators or audience did not merely sit and listen, but could, if they wished, and must, to get the most out of it, be participants.
