See the Wikipedia article on Concert pitch. Crankery associated with musical pitch can be found, but not much of it. The alleged healing properties of Leonard Horowitz's "solfeggio frequencies" come to mind, as does Lyndon LaRouche's Schiller Institute and its shenanigans around "Verdi pitch."

I won't slap a mission tag on the article, but I don't see a lot of RW relevance here. Sprocket J Cogswell (talk) 04:47, 6 December 2014 (UTC)

The A432 movement includes a great deal of gibbering crankery that makes it entirely missional - David Gerard (talk) 11:58, 7 December 2014 (UTC)
In which case the missional article would be A432, yes? For starters, I would add a section on the Schiller Institute's "Verdi pitch" crapola to Lyndon LaRouche, and redirect A432 to that page. But first, let me stash all my 440 tuning forks where the authorities can't find 'em. Also the metronome that beeps an A selectable from 440 to 445.

Never mind. I have come to believe that it suits the RW mission better to let this be the main article, and let A432 redirect here. Sprocket J Cogswell (talk) 16:55, 8 December 2014 (UTC)

If the specificity of the title/topic bothers you, perhaps this can be renamed to "tuning frequency" or "tuning standard" or something similar.--ZooGuard (talk) 16:59, 8 December 2014 (UTC)
That might help with confusion over the road from Malvern to Pershore! Doxys Midnight Runner (talk) 17:11, 8 December 2014 (UTC)
Hrmph. Wikpedia tells me that there is no longer an A440, and that the A432 connects Bristol with Old Sodbury, fittingly enough. For the moment, the present title is OK with me. I've redirected A432 to this page, as a poke in the conspiracists' general direction. Sprocket J Cogswell (talk) 00:42, 10 December 2014 (UTC)

Solfeggio vs. "solfeggio frequencies"[edit]

For centuries, musicians have used solmizationWikipedia as an aid to memory, and for teaching the pitches and intervals of their own music traditions. Western musicians are familiar with "do re mi fa sol la ti do" which Julie Andrews memorably rendered as "doe, a deer, a female deer, ray, a drop of golden sun..." in The Sound of Music. A Hindu musician familiar with sargamWikipedia could use "sa re ga ma pa dha ni sa" to sing the same major scale. Similar systems exist in Arabic, Chinese, Indonesian, and Japanese music cultures. (Drummers in Japan and Western Africa use vocablesWikipedia to express the rudimentsWikipedia of their art, but that is another topic.)

What's the point? You may well ask. "Solfeggio," referring to a form of solmization, is a perfectly legitimate term in wide use, not subject to ridicule under the terms of the RationalWiki Mission (obeisances be made unto it.) "Solfeggio frequencies," on the other hand, are a modern bit of fakelore conjured up by one Leonard Horowitz, based not on any physical properties of sound or vibration, but on numerological manipulation of the decimal representation of fundamental frequenciesWikipedia in cycles per second. Note well, cps (now called Hz) are a recently contrived human means of describing frequency measurements, not magic at all. Sprocket J Cogswell (talk) 15:00, 6 December 2014 (UTC)

An important distinction indeed. The "Solfeggio frequencies" outlined by Horowitz involve an incorrect and nonsensical application of the terms UT RE MI FA SOL LA, which traditionally refer to the notes C D E F G A, but in his framework do not even remotely correspond with these notes either by absolute pitch or by interval. One of the many other signs that it's pure bunk is the fact that the "LA" (852 Hz) of the first octave is HIGHER than what should be the "UT" of the next octave up (396 Hz x 2 = 792 Hz). This is quite a detailed take-down of the whole thing: --Yisfidri (talk) 13:56, 9 December 2016 (UTC)


Stuart Robbins has a podcast all about this, both physics and conspiracy. Worth cribbing - David Gerard (talk) 18:16, 18 September 2015 (UTC)

Interesting, in a "physics for poets" sort of way. He gets it mostly right, in simplified terms, and yet... There were a few places where I twitched a bit, but upon further reflection came to understand that there was some sort of way to reconcile the complexities of the Big PictureTM with his ELI5.
