I think Dr. Art is partially correct in hypothesizing that intellect is related to the enjoyment of more complex forms of music.
HOWEVER.
It is important to point out that this is merely due to a combination of two skills, as it seems:
1. Mathematics
2. Analytical Ability
Mathematics comes into music because, of course, music is a mathematical endeavor. Time signitures keep a steady beat (rule) as to how and when notes can be played. No matter how often the time signitures change, no matter if whether or not they are even taken into consideration when writing/performing music, there is no question that time signitures are a real thing that indeed exist in every musical work. This is the proof alone that music is completely math-based. The more complex and abnormal these time signitures become, the more complex and abnormal the music itself becomes, because, while a musician could technically do anything within the bounds of ANY time signiture, only certain ones will allow the musician to formally perform them. For example, if I'm in 5/4 (which means that there are five quarter notes in each measure) and want to do a crazy accent or something on beat five, or something like that, it would be relatively easy. However, if I were to translate that exact instrumentation to 4/4, where there are four quarter notes in each measure, it would become increasingly difficult to do that, since the accent would actually be on a new measure, on beat one, but next time, it would be on beat 2, and so on and so on. Therefore, if things like this happen, it is the accepted practice to alter the time signature to allow for more complex events. And to conclude, altered time signatures which play more or less than a FULL measure (full meaning not 2/2 or 4/4 or 8/8, which are all in reality the same signatures anyway) are more complex. And normally, you find these kinds of time signatures in progressive rock, jazz music, classical music, and the like. You NEVER find it in pop, rap, or other lowly forms of music like that. This is because they just want an easy beat to dance to, mainly. It would be hard to dance to the 1st movement of Close to the Edge

And then we have bands like Rush, who are complex because they make the very most out of what three men alone can do. Geddy Lee can sing, play bass, and play the keyboard with his feet all at the same time. Neil Pert has hands that act as if they were lit on fire -- he can do amazing things with his drum kit. Characteristics like these are what give bands like Rush, Yes, Jethro Tull, and Gentle Giant "complex" labels. In addition to this, all of these groups were very well-known for performing and recording very unique fusions of different genres and also very abstract solos.
The point is, that there are accepted ideas of what makes music complex or not, but it is mainly in the idea of mathematics. One thing that all music shares with one another is that it has a beat. That in my mind should be the basis of complexity of music - the technical stuff. The math (the beat), the actual physical virtuosity that the artist must have to perform it, the ability/gift/tallent it takes to construct the piece -- these are the only ways in my mind that EVERY form of music out there can be judged in terms of complexity.
And yes, this post is long and the constant rambling will not allow for most people to truly understand what I mean, but at least try

But honestly, sbudiek, what are you on? You talk all about time signatures, but cannot agree that music is completely formulated by mathematics? That's ridiculous...
