'''Solfeggio frequencies''', often promoted as "[[Pseudohistory|ancient]] solfeggio frequencies"<ref>[https://attunedvibrations.com/solfeggio-scale/ The Ancient Solfeggio Scale], ''Attuned Vibrations''</ref>, are a [[crank]] concept in [[sound healing]]. They involve grandiose claims about a certain series of sound frequencies (174, 285, 396, 417, 528, 639, 741, 852, 963 Hz) derived from a [[numerology|numerological]] system of family number groups. The concept hijacks and misapplies terminology (including the name) from the "solfeggio" or {{wpl|solfège}} [[music]]-education method, but other than that, has nothing in common with it. Many who push this woo also push the [[A440]] conspiracy – that is, that the modern international standard for Western tuning is somehow detrimental to our well-being. 

==Claims==
Apparently, an individual by the name of Dr. Joseph Puleo (in mid-1970s) discovered "solfeggio frequencies" through a series of [[pareidolia|pareidolic]] [[numerology|numerological]] calculations involving [[Bible]] verses, and it is claimed that these frequencies are "ancient" and "sacred" and were frequently used and sung [[Appeal to ancient wisdom|before being "forgotten" by the modern world]].<ref name="avass">[https://attunedvibrations.com/solfeggio/ What are the Solfeggio frequencies?], ''Attuned Vibrations''</ref> How we were able to measure the exact frequency of sound back then is not addressed. 

One of the foremost promoters of the "solfeggio frequencies" is [[Leonard Horowitz]], and following his lead, the idea has circulated far and wide over the years on YouTube and among [[New Age]] websites. The following vaguely miraculous claims are nearly always given for each of the frequencies:<ref>[http://themindunleashed.com/2014/02/solfeggio-frequencies-set-body-full-harmony.html Solfeggio Frequencies Set Body Into Full Harmony], ''[[The Mind Unleashed]]''</ref><ref>[http://humansarefree.com/2016/01/6-frequencies-used-by-ancient-cultures.html 6 Frequencies Used by Ancient Cultures to Heal and Connect to the Divine], ''[[Humans Are Free]]''</ref>

In fact, the series is not based on any actual musical, aesthetic or acoustic considerations, only numerological ones. The apparent connections between these numbers hinges entirely on our use of base ten for counting, and would fall apart in most other number bases. In addition, Hertz is an arbitrary unit of measurement that is based on a thirty-one-million-five-hundred-and-thirty-six-thousandth part of one revolution of [[Earth|an arbitrary planet]] around [[Sun|an arbitrary star]]<ref group=note>31,536,000 seconds in a common (non-leap) year.</ref> – hardly grounds for any claims of cosmic significance. In fact, this supposedly mystical numeric sequence is found in the columns of digits on the standard numeric keypad of a telephone or computer.

==History==
The name "solfeggio frequencies" is a complete misuse of the term "solfeggio" (or {{wpl|solfège}}), which properly refers to a [[music]] education method that was developed to teach sight-singing and accurate pitch, associating a syllable with each note of the {{wpl|Scale (music)|musical scale}}. The system originated with 11<sup>th</sup> century music theorist Guido of Arezzo assigning six syllables (ut, re, mi, fa, sol, la) to the first six notes of what would later be known as the {{wpl|major scale}}; he derived these syllables from the words of the Latin hymn ''{{wpl|Ut queant laxis}}'': 
*'''''Ut''' queant laxīs '''re'''sonāre fībrīs; '''Mī'''ra gestōrum '''fa'''mulī tuōrum; '''Sol'''ve pollūtī '''la'''biī reātum, Sancte Iōhannēs.''
Much later, the "ut" was changed to the open syllable "do", "sol" sometimes to "so", while "si" (later changed to "ti") was added for the seventh scale-note, giving rise to the modern solfège that formed the basis for this famous ditty:

===Pseudohistory===
Promoters of "solfeggio frequencies" attempt to intertwine them with the history described above, claiming bizarrely that the tones Guido of Arezzo drew from ''Ut queant laxis'' actually corresponded to this magical series of frequencies — which, by the way, bear no resemblance whatsoever to the medieval hexachord, the {{wpl|Gregorian mode|church modes}}, the major scale, {{wpl|just intonation}}, {{wpl|Pythagorean tuning}} or anything else in Western tonal music,<ref group=note>They can, however, provide an interesting soundscape for modern musicians and composers.</ref> despite claims to the contrary.<ref>[https://somaenergetics.com/pages/forgotten-in-time-the-ancient-solfeggio-frequencies Forgotten in Time: The Ancient Solfeggio Frequencies], ''Soma Energetics''</ref> At any rate, even trying to claim that they originated with Guido's 11th-century concept would not justify the appellation "ancient".

==Further misinformation==
As if using the name "solfeggio" wasn't bad enough, the framework also misuses the syllables "ut, re, mi, fa, sol, la" by inexplicably reassigning them to the "solfeggio frequencies" (396Hz = "ut", 417Hz = "re", etc. until 852Hz = "la"<ref group=note>Note that the frequency of "la" in this system is more than double that of "ut", placing it ''higher'' than the "ut" of the next octave up. To illustrate how silly this is, imagine playing the ascending white notes on a piano keyboard - C, D, E, F, G, A, B - only to find that the next C was of a ''lower'' pitch than the preceding A and B!</ref>) instead of the diatonic scale tones to which they belong. This is quite a disservice to music educators, students, and anyone else who wants to study the solfège method. It is also highly ironic, given the focus of solfège on ''singing in tune'' and the fact that the frequency series is hardly singable at all.<ref group=note>In fact, [http://hwcdn.libsyn.com/p/c/1/2/c124056d12a049ca/Solfeggio_Mystic_Hexachord.mp3?c_id=9355255&cs_id=9355255&expiration=1566788967&hwt=6b6be0ca34a462cd30e648e98df518e0 this audio demonstration] shows that the tones sound rather "out of tune" with each other.</ref>

Unfortunately, the concept is still popular and has been making rounds on the internet for many years, to the extent that the top results of a Google search for the word "solfeggio" include demonstratively [[New Age]] YouTube videos and domain names such as attunedvibrations.com, powerthoughtsmeditationclub.com etc. uncritically repeating Puleo and Horowitz's nonsense<ref>[https://www.google.com.au/search?q=solfeggio&oq=solfeggio&aqs=chrome..69i57j0j69i61l2j69i60j0.2270j0j7&sourceid=chrome&ie=UTF-8 Google search result for "solfeggio"]</ref> instead of actually useful information on solfège.
