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."
Glee!
That shit all sounds the same. Same Autotuned voices that are bland and boring.
Agent K: A *person* is smart. People are dumb, stupid, panicky animals, and you know it.
9 might sound like a small number, but dB is a logarithmic measuring. 9dB louder (please correct me if I'm wrong) mean 8 TIMES louder.

Is it a big surprise that contemporary music sounds alike? They keep sampling each other's songs, with and without permission, and recycling the all sorts of song elements. That is before you consider different bands performing each other's music outright. The current custom seems to produce homogenized music.

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.
Pachelbel's Canon has eight notes...
No sig today...
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."
Those aren't chords. They're keys and their relative minors.
Who knows...I just ask, "What the hell is that?"
I changed the station to something more musical...like Led Zeppelin.
I don't much like anything with unintelligible words, which greatly limits the modern metal I listen to.

They do a good job but they ripped it (unintentionally or not) from this guy's routine. Yes this is the Pachelbel's Canon rant. Pachelbel's Canon is a baroque piece that follows roughly the I V vi IV progression. And as shown in both videos, it's probably more correct to say it's the progressions being reused, and how that is key since it is redundantly obvious that chords like notes are more limited and are always reused. Or like letters in the alphabet... there are only 26 but they can make millions of words (in many languages) depending on how they are ordered, or their progression.
For anyone who this flies over, it is really quite simple. We have seven notes in the traditional western scale (sometimes called the ionian mode by music geeks). In grade school we first learn the musical scale as doe ray me fa so la tee doe. That's eight because we repeat the root (do'h). If we looked at a piano we can play starting from middle C, and get the same scale by playing the key for the C note, then D, E, F, G, A, B, C.
We can also play the scale using chords instead of individual notes, and this is key to understanding progressions. But if we want to play the scale using chords for the C scale (called the harmonized scale), each chord needs to be made up of notes from only the C scale. If we played a harmonized scale in D, the notes of every chord would all need to belong to the D scale. This happens to work not too badly with a couple of minor (small pun here) changes. To keep it short, another important concept is that often the scale is enumerated. The first note of any scale is 1, the second 2. Usually this is done in Roman numerals. So a C in the C scale is I, the B is ii, the E is iii, the F is IV, the G is V, the A is iv, and the B is viib5 (the last one, minor seven flat 5 is a bit messed up, yeah). The upper and lower case is important, because upper case means a major or dominant chord and the lower case means minor.
We use the roman numerals because they can just be moved around to any scale. Say D, where the scale is D, E, F#, G, A, B, C#, D. So I, V, vi, IV as in Pachelbel's Canon, or the Axis of Awesome's Four Chords, is D, A, Bm, and G. Since you know it's I, V, vi, IV you can move it to the key of C and play C, G, A, F. If you were playing blues, the most common progression is I, IV, V (so you'll hear people saying, "hey, it's just one four five", and then often the key). You can hear a musician at a jam sometimes say, "there is a I, vi, ii, V turnaround." A very common turnaround and a type of progression.
So it is these chord progressions (encoded in roman numeral notation) that are really important not so much the chords. Take for example the progression: I, III, IV, iv... That is the first four bars of Radiohead's Creep. But it is also the first four bars of a 1920s Bessie Smith tune called 'Ain't Nobodies Business; covered very successfully later on by Jimmy Witherspoon, BB King and Ruth Brown(key of Bb), and the BOMB, Freddie King (key of Db... with a I, vi, ii, V turnaround :).... and borrowed by Radiohead (no turnaround... and nothing wrong with using the progression, like the article points out, there is limited set of progressions that sound good to people, their going to be reused).
To try to explain the reason for major and minor in a short space (it is is dense but should be understandable if you have even a little musical knowledge): Remembering the C scale is C, D, E, F, G, A, B: The first note is C
