As it is shown also, in some other parts of the book, there is a new form of fundamentalism nowadays: the rejection of the symbolic models by a fraction of the population. That is, some people return to harmony (there are many who prefer Mozart e.g.). The present music is balancing between symbolic-type music (hip-hop or rap e.g.) and harmonic music. This tendency will continue for a long time, because it is hard to believe that music will disappear (the brain is based on image models forever), but returning to the year 1800 type harmony is not possible anymore. Music is defined as a special story-type model associated with sounds. This story-type model has elements generated by an algorithm generator. The generating algorithm is able to build in a dynamically way the elements which will be recorded by this special type story-type model. Based on the algorithm, the model is able to predict the future sounds based on the sounds already received. Sometimes the algorithm generator is able to make a correct prediction of the sound which comes (a hit), sometimes not (a miss). If the prediction fails, then the generator will modify the algorithm and continue to predict what follows. When the number of misses is low, this could produce pleasure to the brain. When the number of misses is zero, there is no pleasure (e.g. a boring music). When the number of hits is zero, there is no music (no correlation between the sounds). As this special story-type model is an image-model, its power is decreasing as the brain is evolving to symbolic models. On the other hand, it seems that the symbolic models support the algorithm generator. That is, there are two tendencies that act in contrary directions. One tendency is to make a simplified music, based mainly on symbolic models (texts) in the frame of a rudimentary rhythm (e.g. drums), as hip-hop and rap music and on the other hand, to make music based on complex algorithms (to enlarge the limits of acceptability). The present music is evolving between these two large limits. The main tendencies of the present music are: - The evolution based on symbolic models. This tendency increases the limits of acceptability of what are and what are not correlated sounds. - The rejection of the symbolic models by a fraction of the population, i.e. people want harmonic music. - The return to harmony is possible only partially because many abilities associated with the main story-type model are lost, due to the general tendency of conceptualization of the image models. That is, the algorithm generator is better and better, but it acts on recorded data, which are a simplified copy of the external reality.
