  1. I’m surprised that there’s more major than minor key in EDM/Dance. When I go to Beatport.com it looks like most songs are in minor keys. Also it would just make sense for EDM to be mostly minor because it’s so repetitive, so minor chord progressions keep the tension through the songs.


  2. Your methodology is flawed. You exclude 1) the possibility of no key. 2) the possibility of multiple keys. 3) modes.

    A key is a subjective organizing principle of tonal composition, not a property of frequencies.

    Your method commits confirmation bias: you only find what you are looking for.

    1. Yes a key is arbitrary organization of tones guess what a tone is smart guy…. A FREQUENCY!!!!! Yes there is atonal 12 tone scale music and modal music but, even these have cords which, more or less fit into one of the classical major and minor scales. They even more or less said this was based on rough estimates which, is not the same thing as confirmation bias. I venture to guess some of the results surprised them like the fact jpop actually rivals classical for using all the scales more equally than a lot of other genres. Another one that might have suprised them is the fact metal doesn’t use as much minor as you might think. No, think you’re projecting and the results somewhere contradicted a preconcieved notion you had about a genre or two or even more.


  3. Interesting that there is a greater percentage of major keys than minor keys in virtually ever genre listed here. The algorithm may detect what scale the frequencies of a song best fit to, but how does it detect the difference between a major key and it’s relative minor? I suspect a flaw.


  4. Thank you for this great article, loved it just like your first foray on key signatures. I cant wait for the next one on the key changes and maybe the next ones could be focused on chords and chords progressions ?


  5. If they didn’t have an algorithm which, could estimate the difference between a major and minor scale they wouldn’t have posted the results simple as that.


  6. I do have some issues with these results. For example I venture to guess a fair part of the reason why jazz has such a high frequency of major keys especially C major is cause they are counting New Orleans Traditional as well as swing. If they separated traditional jazz from modern ( bebob, modal jazz, fusion) the results would be fairly if not quite different for both. Also, I estimate the reason why Major keys are so high for Metal is cause they are counting hair and glam metal if they had a separate category for hardcore the results would different in a stark matter.


  7. Also, the tag line of different styles of music use different scales is erroneous. It should read different styles use a different frequency of musical scales.


  8. Key is plotted chromatically, C to B. It may be interesting to see Key plotted according to the circle of fifths, with C in the center, so that we could see how the results may be clustered around C, G and D.
    Also, perhaps the minor keys could be plotted with their relative majors (a with C), etc.
