There’s an interesting blurb from Tyler Cowen on why he thinks Desi music isn’t as popular in the West as other types of world music (at least for now… times are always a-changing, of course). Asked by a reader –
Why do the US (a wealthy country) and Africa (a poor continent) put out more influential modern music than Asia (a populated continent of both wealthy and poor extremes)?
Tyler responds –
3. The micro-tonal musics, as we find in India and the Middle East, don’t spread to many countries which do not already have a micro-tonal tradition. Cats wailing, etc., though it is a shame if you haven’t trained your ear by now to like the stuff. It’s some of the world’s finest music.
4. Many Asian musics, such as some of the major styles of China and Japan, emphasize timbre. That makes them a) often too subtle, and b) very hard to translate to disc or to radio. African-derived musics are perfect for radio or for the car.
The comnentors also make some important points. For example, even though we don’t see desi tunes in the West very much, they are all over the rest Asia (outside China/Japan/Korea), the Middle East, Africa, and even some former eastern block countries. Second, most Indian pop music it is driven by the film industry rather than by a separate “music” industry. Another commentor further expands Tyler’s point about the micro-tonal aspects of Indian music –
While there is no contemporary popular style that uses the scalar melodic microtones of the Ancient Greek enharmonic scale, both the Islamicate and Indian (Hindustani and Karnaktic) repertoires use intervals that differ audibly from the Western tempered scale by microtonal intervals, thus the Islamicate scales use both intervals very close to the western semi- and whole tones, but also intervals close to three-quarters of a tone and somewhat wider than a whole tone (with a ratio of around 8:7). A scale approximating a western diatonic scale is possible in both these repertoires, but is only one among 18 or so in wide use in Arabic/Turkisk/Persian music and among significant many more in Indian practice.
I’m going to go way way way out on a limb and toss out another personal, vastly underinformed, pet theory on this question. Instead of musical structure, language barriers, and the like I also wanna toss in some cultural context…
