Study Finds New Pop Music Does All Sound the Same
whoever57 writes "A study of music from the '50 to the present using the Million Song Dataset has concluded that modern music has less variation than older music and songs today are, on average, 9dB louder than 50 years ago. Almost all music uses just 10 chords, but the way these are used together has changed, leading to fewer types of transitions being used. Variation in timbre has also reduced over the past decades."
So it isn't just me?
Glee!
That shit all sounds the same. Same Autotuned voices that are bland and boring.

Eh.. Only four bases used in your DNA. What's your point?

Youngster. Most of Status Quo's repertoire was three or four chords, but they played them insanely well.
A good example of a popular song that uses just three chords and a single note for the main melody is "Ça Plane Pour Moi" (and it's variety "Jet Boy, Jet Girl" which uses an excess of two notes for the melody).
And minimalists like Kraftwerk, of course.
But then at the other end of the spectrum, you have music like Mike Oldfield or Vangelis that can use dozens of chords, counterpoints, and an enormous frequency range with both timpani and walking treble, yet sounds simplistic.
And then you have symphonic rock like Yes, Pink Floyd, Genesis and King Crimson which sounds awfully complicated, but seldom is. Five chords is pretty standard, but shifts between major and minor, tempo shifts and synth embellishments makes it sound a lot more complex than it really is.
But yeah, music from the oughties tends to be on the simpler side no matter how you look at it. In-your-face with little or no dynamics, a substantial lack of treble, and the lyrics being more important than the melody. And that's just fine - people have different tastes, and the pendulum will sooner or later swing back again.
If you play Beethoven's Fifth and Seventh, I think you would have a hard time making that claim. And that's not even comparing him to Mozart or Wagner.

The purpose of popular music was never to provide musical diversity and variety. At root, it's a folk art form and like all folk art forms, it's going to be stylistically similar.
If you look at the popular music of 16th century England or 19th century America (the two countries who have the biggest effect on worldwide pop music) you would probably find even less musical variety than the music of today.
Also, remember, that the 1950s, the era that this study compares to our current era, there was a confluence of some very different musical forms making up "pop music". There was big band music, with roots in Jazz and the American Songbook, there was country, blues, R&B all collapsing in on each other to form the popular music of the day. You might hear Tommy Dorsey, Frankie Lane, gospel, Louis Jordan, Hank Williams. Top 40 radio of even the 1960s would have the Beatles fighting it out for the top of the charts with Sergio Mendes, elements of deep country, Frank Sinatra singing "strangers in the night" and Sonny and Cher, folk music, etc.
But the biggest influence on the homogeneity of current popular music is the concentration of ownership of media outlets. You have a handful of companies owning 90% (or more) of the radio stations in the US, for example. You scan the dial in LA, Chicago, New York, Memphis or Rolla Missouri and you're going to hear the same top 20 songs, the same "classic oldies" stations, the same "urban contemporary" and they're all owned by the same companies, using their market position to put the same exact formats (and often the same exact program directors) on all of the stations in any given category.
The days of the independent radio stations is over. Satellite radio was supposed to offer variety, but now there's even a growing concentration of ownership in those stations. And who sells all the records? Wal-Mart, Best Buy, and other chains, who really aren't going to give you much variety.
It's not the music that's lacking variety, it's the economy.

Woody Guthrie said that if you're using more than three or four chords in a song you're just showing off. And a lot of the garage bands of the 50s-70s started off only knowing four chords, and that was really enough; you could always transpose if you didn't know the chords.
I play a few genres of traditional music - old-timey, Irish, a bit of bluegrass, some folk, some German. I mainly play mountain dulcimer, which is a diatonic instrument, so changing keys is annoying, since you have to retune, as opposed to guitars, pianos, and accordions where you've got the whole chromatic scale there. It turns out that there's a very wide range of music that not only uses only 3 or 4 chords per song, but always uses the same scale because that's friendly to the fiddle player or piper, and also if you don't have many strings, you can't play very complicated chords. But just because it's the same few chords, that doesn't mean the melodies aren't complex and/or weird, and I don't think they were measuring that.
So it's I, IV, V (or V7, especially for blues), and maybe a VII or the minor ii or minor vi. And the key is usually in D or G, or E minor for Irish, or A for old-timey (though the A tunes might not be an major scale - they're often Dorian or Mixolydian, which are a bit minor, though the chords will usually still be A, D, G, and sometimes E.) So the chords end up as D, G, A, C, and occasionally E or Em or Bm.
French traditional music seems to mostly use a C scale instead of a D (so it's like playing on the white keys of the piano instead of transposed up a whole step.) I've been doing some German beergarden stuff recently, and it's been all over the map - most of it's 3 or 4 chords, but maybe the key is C or F or Bflat (which is brass-friendly), and there are a lot of 7th chords because accordions are good at those and they sound a bit schmaltzier.
And yes, the jazz and classical people always did much fancier chord work. And there are a lot of amazing guitarists out there, and sometimes if you can't figure out how they played something it was because they're using alternate guitar tunings to get different chord inversions, or they threw in an ARRR-flat-7th-diminished-dominant9th chord just to add some color or because it matched the lyrics or covered up the horribly wrong note the bass player had just played. (By contrast, if a bluegrass guitar wants to show off, it's more likely to be by playing a riff extra-fast by adding grace notes, or by throwing in a few bars from another well-known song that's related in some way. And if Woody Guthrie wanted to show off, he'd doing it by writing some really incisive lyrics or getting the audience to go on strike.)

Without checking the TFA, I'd say, at least with more traditional pop songs, it all stems from the fact that certain keys are far easier to play with guitar than the others.
The most popular keys are majors A, E, C, G, and D. Take four basic chords in any of these, you end with
A D E F#m
E A B C#m
C F G Am
G C D Em
D G A Bm
So we have C, D, E, F, G, A, B majors and C#, E, F#, A, and B minors. That makes 13. Add Dm, and you cover most used minor keys, although pop music usually uses major chords (combined with minor melodies).
Some of these minor chords are probably pretty rare, and on the other hand the usual range of singers is another restricting factor. I actually don't listen to pop music enough to rememeber how this affects.
Hey, Beyonce's music shows a great deal of variation! She covers all themes from "I strong independent woman and I gots my man but why he not put ring on muh finger?" through to "We honeys be single confident woman dancing and whooping, and 'aint gon be needin' no man to put a ring on us fingers". The music itself is just as varied and interesting as her lyrics.

So the vuvuzelas at the World Cup were just ahead of their time, eh? :)
Movies are mixed with absolute reference levels in mind. The THX theater spec is 105dB peak for the mains, 115dB peak for the sub. That is the actual level to which movies are mixed. Doesn't mean they have to reach them, but it means they can. A calibrated, THX compliant home system will be able to reach 105dB when the volume dial is set to 0dB (they backed off on the sub for home, requiring only 105dB as few would be willing to spend the money required for 115dB).
Movies are set up to be able to have big hits, and action movies use them. Speech is often 30-40dB below the peaks (Dolby tracks contain encoding letting the decoder know the dialogue normalization relative to peak).
Also in terms of sound, it isn't a 100% subjective "just get used to lower levels" thing. Your perception of loudness is not equal across frequency bands. Have a look at the Equal Loudness Contour graphs (http://en.wikipedia.org/wiki/Equal-loudness_contour). These show at what level a signal must be played to be perceptually equal per frequency. So if you wanted to listen to music at 40dB for the midrange, which is barely over the noise floor of most houses, you would need the lowest bass frequencies to be near 100dB to give equal loudness. However moving up to 80dB for the mids, you only move up to 120dB for the lowest sounds.
So just reducing the volume does not give the same sonic experience unless you re-equalize the track. For movies with their soundtrack encoded at reference levels on disc (something you don't find as often as you should) there is technology to do so on higher end receivers like Audyssey Dynamic EQ and Dolby volume, but it is hard to do for music as there is no reference standards.
You also run in to the problem of signal to noise ratio. Anything less than 40dB (meaning a signal 40dB above noise) is pretty easy to notice, and you can hear more than that. Well, if your room has an ambient noise level of 30dB, which is pretty quiet for a room in an urban setting, you need 70dB average signal level to get 40dB of SNR.
Finally, if you want music that is largely or completely devoid of dynamic compression, you need a good deal of headroom. Many instruments can have large transients. So for example if you want 20dB of headroom, you'd need playback set to do 90dB for a signal that was 70dB average. Pop music doesn't do that, it is squashed to all hell and gone, but classical can. As a simple example I have a track that I mixed from an old videogame MIDI using real sampled instruments. It is normalized to 0dBSPL (as you do with digital tracks), however the RMS level is -17.5dB. So you need to set the volume dial 17dB higher than the average level you wish to maintain, because it has large peaks (this is in an unprocessed state, no compression applied).
While I'm all about not abusing the volume dial and hurting your hearing, sound perception is more complex than "Just turn it down and you'll get used to it."
