Chords To 1300 Songs Analyzed Statistically For Patterns 132

Posted by samzenpus from the math-of-music dept.
First time accepted submitter hooktheory writes "We looked at the statistics gathered from 1300 choruses, verses, etc. of popular songs to discover the answer to a few basic questions about pop music. First we look at the relative popularity of different chords based on the frequency that they appear in the chord progressions of popular music. Then we begin to look at the relationship that different chords have with one another. To make quantitative statements about music you need to have data; lots of it. Guitar tab websites have tons of information about the chord progressions that songs use, but the quality is not very high. Just as important, the information is not in a format suitable for gathering statistics. So, over the past 2 years we've been slowly and painstakingly building up a database of songs taken mainly from the billboard 100 and analyzing them 1 at a time. At the moment the database of songs has over 1300 entries indexed. Knowing these patterns can give one a deeper more fundamental sense for how music works" This reminds me of the work done by two Rutgers grad students last year trying to find a formula for a hit song.

      Just what we need, a database for the RIAA to use to play Whack-A-Mole on upcoming songwriters for 'copyright infringement'.

      This type of analysis has been going on for decades. I remember meeting a guy [circa 1992] who had a consulting business based on doing just that. He would put a [suspect] music CD into his CDROM drive and [with custom software he wrote] have it analyze the note sequences looking for fragments that matched fragments of his clients' songs/catalog. IIRC, the criterion was either 11 notes or 11 bars [I can't remember which] of music.

      There are only so many chord progressions possible.

      Per copyright law, things that have "only one way to do them" can't be copyrighted. Also, the work must be of sufficient length (e.g. a 3 chord sequence could not be copyrighted but a 50 chord sequence could). Although circuit courts have varied on this, in general, the courts have held that to grant a copyright on a short [enough] sequence is tantamount to trying use a copyright to get patent-like protection. For the most part, this gets rejected.

      For specific examples of this, read Alsup's decision in the recent Oracle/Google dispute (including the citations to precedents). Or the second Westlaw mashup (again with citations).

      This will allow the holders of the eternal copyright to sue somebody because the chord progression they wrote mirrors a song their grandparents heard in the womb and thus infringes.

      IIRC, just having a long chord sequence that matches isn't always grounds for claiming infringment. In particular, if the defendant can show that they got there through non-infringing means (e.g. they kept all their composition sheets and could prove that they created the work from scratch, it's not infringing even if a portion happens to match). Unfortunately, I can't recall the case law to cite for this [just an article I read way back when].

Also that different styles of music vary along different parameters. Expecting a brave new chord progression in most styles is silly. And, in those styles where you're supposed to expect "original" chord progressions like prog rock, they usually turn out to not be all that original in the big picture.

        Yes, I would agree, my Minor was in music, and in Music theory classes, they gave us a list of the Bach Approved Cord Progressions.
        This has been the gold standard in Western Music for hundreds of years. Too much variations of this will sound unmusical to western ears. Popular music is about being familiar, It has been for a long time, so popular music will not stay away from the familiar. That is why professional musicians can just jam with a brand new song, by hearing where the song is and where it has been, they know where it is going to go.

        When you "Break The Rules" which you are allowed to, use need a good reason to do so. Give music that extra spice, but it is akin to a jalapeno on a burger, vs. just eating a plat full of jalapeno's (if you break the rules for no good reason)

        The Tonic (I cord)
        and the Dominate (V Cord) are usually always work with each other. The Subdominate (IV cord is sometimes used too, because it is the inverse of the Dominate). The Submediant (VI Cord) is the natural minor code with the same key Signature of the Tonic cord.

        Now the Supertonic (II Cord) is often due to a secondary dominance (The V cord of the V cord) Or used to move to a minor function from a Subdominate(IV cord).

        The Mediant (III Cord) and Leading tone (VII Cord) are used very sparingly. Primarily because the Median and the Leading tone, are key notes in letting the listener know what mode the music is in Major or Minor (The VII also can tell if you have a Natural Minor or a Melodic Minor). So these notes are usually reserved to give the music its feel, and not be the boring job of being a Cord Root. Now you may see the III and VII cord in music, however they are often not really a III or VII cord anymore, they are part after a key change in the music (often due to Secondary dominance) and sticking to the new key, for a while (now the music may have a new key signature, or just more accidentals in that area).

      BTW, the reason for the popularity of many chords (or lack thereof) is likely because so much pop music is guitar-centric. An A major chord would only be common if you're playing in D major, E major, A major, or sometimes in D minor (with a raised 7th).

      • Playing in D major isn't great for solo guitar work because with standard tuning, you've lost the fundamental. Now if your guitarist is willing to keep an axe in drop-D, sure, but....
      • Playing in E major results in having to play a B major chord as your V, which is kind of a clumsy chord to play (compared with many other non-complex chords, anyway).
      • The key of A major is awkward for tenors. Although the middle A is comfortable, the high A is powerfully high, and the low A is below the bottom of their usable range, so you can't safely write music that spans an octave from tonic to tonic. And even for guys with lower voices, the low A just sounds too boomy.

      You'll notice that D, major, A major, and E major are the 5th, 6th, and 7th most popular keys. And although D minor is the 4th most popular key, not all A chords in D minor are going to be major chords.

      I would also expect the probability of moving from any given chord to another would be strongly correlated with the standard chord leading rules, assuming you analyze them with numbered chord notation rather than by the actual note names. Certain chords naturally follow other chords, and although you don't have to always use such pairs in that order, good composers will tend to do so the majority of the time.

Unless the nut is compensated as well most fretted notes are out of tune a bit till you get to the 12th and 24th frets. This makes many chords, comfortable or not, out of tune.

Now play your open position C against this.

          It is far easier to understand beginning with common tuning systems. Originally, stringed instruments and keyboards such as the piano could only play in a few keys.

          I don't think that statistical analysis can glean anything terribly interesting other than confirming what we already know. Sure, an authentic cadence sounds satisfying, and because of that it's always going to very popular. But for anything even moderately more complex, most of it is going to depend on cultural factors for whether or not it becomes popular.

          Just look at the history of blues changes in western music. Go back 200 years and Beethoven was the only major European composer playing around with the V-IV progression IIRC. Most people absolutely hated it, and it sounded completely foreign to their ears. They nicknamed it coitus interruptus because it did not resolve "properly." Then blues explodes in the US, and from the 1950's on that's one of the most common progressions in Western music. Then in the 1970's everybody's so tired of blues-based rock that it gets passe again. It sounds boring. So over time it went from sounding unnatural and experimental to being so common that it was uninteresting to many musicians. Nothing about the actual theory or function of the chords changed, just cultural factors.

          Plus, it would be pretty difficult to do. Even if you spent a great deal of time on each song, it would be difficult to give consistent interpretations. Is that iii substiuting for tonic? Is that a tri-tone sub of the V, or just a passing chord? Things like that.

  • Don't let the RIAA get their hands on this technology. They will just start suing all the off-label artists for stealing their valuable "copyrighted" chord progressions.
    • Dude RIAA has known this for milennia. This is why they often don't even wait for talent to come up with their own songs, but click on their computer,"Create Song.", then they teach a random cute or outrageous looking young person how to sing to it.

    Anyone with a rudimentary understanding of music theory could have told you that. It's not just pop songs either, composers have been using that progression for hundreds of years in every conceivable genre. It goes back to the very beginning of what we would consider standard harmony, circa late 16th century, maybe earlier.

  • Strangely, they found that a vast majority of popular music from the last 60 years seemed to break down into a pattern of 48 beats using three repeated chords (and variants thereof), such as: AAAADDAAEDAE. Odd that.

  • What kind of software did you use for your analysis?

    What kind of chord information do you see when you analyze something like one of the sections of Vivaldi's For Seasons pieces? I'd say borrow a Vivaldi score and then run your analyzer on those blocks of violins that are sawing away in something like the Summer or Winter pieces. The Vivaldi tunes are really "wall of sound" or "wall of musical excitement" pieces. But underneath all the flashy richness of multiple violins playing I wonder would your analysis

    It really doesn't matter, so long as you have a good marketing department.

  • Just about every pop song for the past... eternity... has used the same pattern: I, V, vi, IV. It's hilarious how bad it's getting. For instance, look at the preview of Coldplay's "The Scientist" [musicnotes.com] on MusicNotes. The original key is F Major, so we'll work off of that. We start off with a Dm chord, thusly iv (minor sixth). Transition into Bb Major, so we get IV (major fourth). Then down to F, so I, and finally to C, so V (major fifth). They just shifted the pattern two chords over.

  • to consider that music needs ONLY a succession of notes happening in predefined patterns in order to please people !!!

  • Couldn't he at least have used that system and then told us the most common chord sequences as well as the most common keys...

    The science fiction author Charles Sheffield wrote a story about a similar idea in the late 1970s called What Song the Sirens Sang [baenebooks.com]. The protagonist is a journalist investigating a politician who has come seemingly out of nowhere and is about to be nominated for president. He discovers that the secret to the politician's success is that he has developed a theory of communications that allows him to combine words and music to evoke optimum emotional responses. Check it out, it's a short read and very good.
  • A recent study of the "Freie Universität Berlin" of trends in US charts suggests, that pop songs got slower over the last 50 years and use more minor chords. Doesn't mean that society got sadder, the study explains, it only shows that we listen to more ambivalent stuff and are able to enjoy even sad emotions.
  • I'm sorry, but the reserch won't tell anything interesting. For a song it is much more important, HOW it is performed, not WHAT is performed. There is no (naive) formula there, that a computer could analyze. The success of a song has everything to do with the charm of the artists and how skilled the musicians are and how it is arranged and so on. The chord progressions are irrelevant. Look, this song [youtube.com] had only 1 chord and it was a huge hit. So what now -- we start writing 1-chord songs and every monkey could

  • The coolest app ever would be one where you hum, whistle or sing a few bars of a song you know, or almost remember, and it identifies the song for you. Of course said app would have to know all the songs in advance in order to find a match. Yeah, that would go over big with the RIAA.

    So the juicy stuff comes next month?

    I did something similar on a smaller scale recently for a still-in-progress hobby auto-composing app using cSound and scripts. I took chord progressions that I personally liked and built a chord pairing chart something like:

    A --> C
    Am --> F, Em, Dm // note: m=minor
    A# --> G, D#, Am
    B --> D, F
    etc...

    The first chord is the "lookup chord" and the second is a list of candidate "good" chords. In a loop it produces a chord sequence
