Can WolframTones compositions have meaning?
That’s a complicated philosophical question. There’s some discussion of meaning in the computational universe in A New Kind of Science. It’s probably fair to say that objects in the computational universe–and WolframTones compositions–develop meaning as they get connected to other things. In some ways WolframTones compositions are like objects in nature: their features emerge from specified underlying rules. So if the form of a sunset, a tree, or a mollusc shell is meaningful, then so can a WolframTones composition be.
