The other day I read a technical article about music, a subject in which I have great interest, but less talent, except for appreciating it. According to the article in the May 2011 issue of Discover, a scientist investigating the structure of music used the technique of lossless compression [“which exploits repetition and redundancies in music to encode audio data in fewer bits without losing content”] to analyze the structure of musical compositions. He discovered, amazingly, that pop music was far more complex than classical music.
Although no one has yet pointed it out, so far as I can tell, he was wrong.
His rationale was that when he used the lossless compression technique, popular compositions only shrank to sixty to seventy percent of their original volume, while compositions by Beethoven shrank to forty percent of their original volume. From this, he deduced that, underneath the apparent complexity, classical music must be composed of simpler patterns,
Duhh!
All music is composed of, or built up from, simpler patterns, including pop music and rap.
What he apparently isn’t considering is that classical music pieces are far, far longer than pop pieces, and incorporate a complex structure that contains repetitions of motifs, restatement and re-orchestrations, etc., all of which can be encoded in such a way as to compress the music to a greater percentage than can be done with a simpler and shorter work of music.
By way of analogy, take the statement, “Mary had a little lamb.” There’s no way to reduce that statement more without losing clarity or meaning. You might be able to remove the “a,” and get a reduction to 94%. Then take something like, “Sheep (Ovis aries) are quadrupedal, ruminant mammals typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Although the name “sheep” applies to many species in the genus Ovis, in everyday usage it almost always refers to Ovis aries. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep.” The second passage can indeed be reduced in volume without losing meaning, possibly by twenty to thirty percent, but because it can be reduced in size more than the first statement does not mean it is simpler.
The scientist is question appears to be drawing the wrong conclusion from correct data, or using accurate but incomplete data. This is, of course, an age-old human failing, which includes the Ptolemaic astronomers who created elaborate models of the solar system with the earth at the center. When I was an economic market research analyst I saw this happen more than a few times, where senior executives would look at the data, which was as accurate as we could make it, and then draw unsupportable conclusions, like the senior executive who used reliability findings to support developing a technically superior compoment that no one would buy because the customers didn’t need a component that was reliable for 30 years when the product to which it was attached had a useful life of five years.
In the first case, that of the compression of music, long classical pieces can be compressed more than shorter popular pieces. That’s a fact, but it’s not because the popular pieces are more unique, but because they’re shorter and simpler, another bit of data not considered by the scientist in question… and a reason why some scientists end up in trouble, because they don’t think beyond the scope of the problem they’ve addressed.
And… most likely, the fettered simplicity of pop music is exactly why it’s popular… because listeners don’t have to work out all the patterns.
