Testing 432 Hz Frequencies (and temperaments)

now let me tell you all about the music that y'all listen to on a regular basis it's played through bad frequencies [Music] look it up on YouTube bro look it up right now when y'all done with this video so in order to compare 432 versus 440 I just detuned my piano by about 32 cents it's the difference between 14 and 40 Hertz in fortune 32 Hertz this is what all the apps do that claim to convert your music to 432 Hertz they just D tune it by that factor 432 Hertz apps you could play all your music and everything through this app the important thing though is that it's not changing the temperament the distance between each one of these notes in the scale remains exactly the same as it does in 440 we use a twelve-tone equal tempered system that doesn't bother me but the big reason why people keep talking about 432 is because of its frequency relationships it's played through bad frequencies if we simply keep the equal tantrum hit at 432 we won't get these better frequencies so what I'm gonna do is I'm gonna reach in my entire piano to these better frequencies whatever they are there's a problem though there are many different sources online that give different values so we'll try a couple of them the first source we're gonna check out is a documentary called sonic and geometry the language of frequency and form which has almost 2 million views on YouTube let's check it out the tuning method required to reveal geometric shapes is based on a mathematical grid rather than mathematical ratios this grid if it had a name would probably be called something like factor 9 because the number 9 is found not only in the sum of every note on the grid but also as the number required to move up or down the scale ok great we have our chart so I'm gonna use the software called piano tech which is super powerful it lets me tune to very specific frequencies first we're gonna go to 432 Hertz of course then we're going to go to advanced tuning we're going to select and make sure that a is right situated there we select frequencies and then boom we have a equals 432 Hertz at the top now we can just type in whatever we want for the rest of the notes so instead of four hundred and seven point eight Hertz ooh that's bad math we're gonna find Oh a-flat should be 414 Hertz much better now you might notice on this chart that there's both G sharp and a flat here which are n harmonic they're the same thing in our equal-tempered system we're gonna just kind of ignore that for right now and move on to figure out what G is supposed to be it's supposed to be 378 Hertz type that bad boy in F sharps 360 F is 342 e is 324 d sharp is 306 D is 288 C sharp is 270 C is 252 B has 234 and a sharp is 225 so now that we've retuned this factor 9 grid let's hear how music sounds with it check it out [Music] that didn't sound all that harmonious to me like it's some greater expression of musical truth than beauty in the universe to me that sounded quite dare I say out of tune is played through bad frequencies well it turns out the way that musicians play their instruments and tune their instruments has less to do with specific frequencies and much more to do with the relationships between those frequencies what we have found is that our ears generally like simple relationships between two frequencies the number of the frequency just doesn't really matter to musicians it's that ratio that matters we currently use a twelve-tone equal tempered system to tune our musical instruments which not only does a pretty good job of approximating these ratios does a pretty good job of approximating them in quite literally every possible key which means that our current system is very very versatile we can use it to play basically any style of music the same really can't be said for this whole a 432 factor 9 system it's a just intonated system that can only really be played in the key of a if it's gonna sound in tune and even then we have to be very cognizant of the exact ratios that we're using any way we can find the ratios between all of these numbers right here by going into piano tech and clicking sensor ratio and then we have our just into nated ratios for us to dissect a couple of them are gonna sound really good the relationship of a to c-sharp that major third is a five-to-four relationship some of these relationships are really strange though like 13 to 12 I actually don't really know what the name of that is hold on one sec yeah so there's this website which is a list of like all the English interval names and you get the basic ones like major third in perfect fifth all the classic ones but then 13 against 12 is the Tri decimal 2/3 tone whoo that sounds really weird and out 23 against 12 that's another strange one 23 against 12 again that's the vie scimitar advise my scimitar shil major 7th hmm that's strange you got a couple other strange wins in here with 7 against 4 which is the harmonic 7 which sounds kind of nice so I'm gonna improvise a little bit in the key of a so you can hear how the system works and see if you like it I don't know maybe you will [Music] okay so some of that sounded a little strange but to me some of it didn't sound all that bad actually it is very limiting though if the point of music is to express thoughts and feelings the thoughts and feelings that this particular temperament and tuning system has to express are in my opinion fairly limited so let's find another one this is not the only one out there so this chart has chakra frequencies and then their correlations has all the different notes not everything in the chromatic scale but will do as much as we can and then their corresponding chakras I don't really know much about chakras but we'll play those frequencies on the piano and see what kind of music we can make with them okay we typed in these bad boys this is what they sound like [Music] okay dare we improvise some music let's improvise something so maybe we're targeting too many chakras at the same time that certainly was a lot worse than the last ones it's played through bad frequencies if we check out the ratios between these frequencies we find some some pretty strange ones like the distance between A to C sharp is 23 to 18 which is the Vice scimitar shil major third this chakra tuning also doesn't contain a perfect fifth which is really strange the ratio of three to two every culture across basically all of human civilization has included tuning temperaments that have at least a perfect fifth in it and this doesn't the closest that it has is a 13 against 9 ratio which is a tri decimal diminished fifth so clearly with this chakra tuning these numbers are not really designed for a tuning system for musical instruments according to this chart anyway musical tuning doesn't quite line up with our chakras and if we did try and line it up with the chakras like we just did it would sound really weird musically it's played with bad words let's check out one more option with 432 temperament this is a Pythagorean tuning or at least a version of it allegedly if you take the Schumann resonance which is supposed to be the resonance of earth about eight Hertz you can calculate a 432 using Pythagorean tuning this is a chart that has it with nice Pythagorean tuning based on the Schumann resonance so let's just type that into piano tech 432 384 we're doubling up on a lot of these because it just has the white keys so we're just gonna worry about those 384 ok so now my keyboard is a nice Pythagorean tuning with all these nice even numbers not these decimal points with modern standard tuning yeah now this is the good stuff let's listen to it [Music] okay so there's clearly something wrong here what is it well it turns out that these are not the frequencies of Pythagorean tuning there's a little bit of a deception going on here normally to get Pythagorean intervals what you would do is multiply C for example at 256 by 3 over 2 the ratio of a perfect fifth and you would in fact get G equals 384 that's good math however to get the frequency for F which is a perfect fifth down from C you would invert the multiplication so instead of multiplying by 3 over 2 you'd multiply it by 2 over 3 so C 256 times 2 over 3 is 170 point 6 repeating yeah that number doesn't look right it's like all decimal point e this number of F 176 looks a little bit nicer because there isn't a decimal point even though the ratio of 170 point 6 repeating relates back to C by a simpler ratio in this case f relates back to C by the ratio of 11 to 8 11 8 was not a Pythagorean ratio it was simply chosen because the numbers look nicer not because the music that they make sounds better is played through bad frequencies in piano tech we can actually just select the Pythagorean temperament with 432 and some of the numbers don't look right but they are Pythagorean in their conception [Music] you [Music] okay so there's a weird chord in there but for the most part it sounded okay it sounded doable we don't really use Pythagorean tuning all that much anymore because it's not the best for harmony a lot of the thirds don't end up sounding very in tune instead we generally use twelve-tone equal temperament because it's so much more musically versatile you [Music] so if you like 4:32 i hope this video has made you think a little bit more about what you read online in terms of frequency pretty much everything out there I've seen has nothing to do with actual music making it's just trying to get the numbers to look a certain way musicians across all cultures have been working on problems of tuning and temperament for quite literally thousands of years and all the discussion I've read online so far about 432 has completely ignored that body of work instead we get this really weird numerology which doesn't have any basis in actual music making as you heard in this video listen I do know that there's this feeling that things are profoundly wrong right now and it might feel nice to try and justify that feeling by saying well what if we were tuning music incorrectly this entire time music affects us in our bodies in a very deep and meaningful way so if we were tuning music incorrectly it would affect us negatively I understand that feeling and honestly if you like the sound of equal temperament in 430 to better than 440 more power to you there's plenty of reasons why that might be might sound warmer and darker you might be able to sing in 432 a little bit better but once you try and justify this stuff with frequencies and numbers and pseudoscience then there's a certain arrogance that's involved because a lot of people will say these are the frequencies we should be using without actually trying to make music using those frequencies in the first place as you heard in this video those frequencies can sound quite chaotic and quite spicy might not be the emotional sort of situation that people who like 4:32 are going for I for one kind of liked it sometimes but there is that disconnect there so if you like any of this stuff try make music with it first before you say these are the frequencies that you should we wake up in the morning you listen to your favorite song out of nowhere you start filling anxiety depressed it's not the song foot is not so far it's nothing wrong with the frequency that that's on the plan so our one shot to look up 432 HZ vs. 432 [Music]
