BRAIN WAVE FREQUENCIESThese are not actual brain waves, but are at the same tempo
"Hz" = Hertz or Cycles per Second aka "CPS", Metronome Tempo = beats per minute.
These samples are TEMPO GENERATED unless specificed TONE GENERATED (New Improved: The Tempo generated samples have been raised from low frequencies, to gamma tones at specified tempos (due to beta contamination).
If your speakers can not play notes this low, try headphonesDelta waves 2 hz (cps: cycles per second) DEEP SLEEP
Theta waves 4 - 8 Hz (cps: cycles per second) MEDITATIVE and SLEEP
YOUR BEST BET:
MU (alpha) waves, TEMPO GENERATED (BEST) AND 2010 percussion version percussion MU (alpha) waves 10 hz (cps) brain wave speed with CALM MIND. {Tempo: like a military helicopter, or bang the bongos extremely fast, or alternating double handed hand face down slaps to a table surface as fast as possible, as in samples.
LISTEN to the tempo generated 10Hz (above) first, then listen to this tone generated sample, they should be both the same, in that they sound like a helicopter.
Note: the TEMPO generated Alpha midi above, is much better and more reliable than the Tone Generated file (below). The Tone Generated one sounds more interesting, but it starts out a bit fast, potentially Beta, so for serious ALPA needs, stick with the one above
"Alpha" or "MU" wave explanation: CONDUCIVE TO GOOD BEHAVIOR, CALMS PEOPLE DOWN (and may prevent epileptic seizures). John Sinclair SR of Little River CA pioneered biofeedback on a government grant related to epilepsy control using biofeedback. I knew John personally, and as to if hearing certain frequencies affects the speed of ones brain waves, was at the time debatable. However, he hooked electrodes to my scalp, and let me hear my own alpha waves (he said I have a strong "alpha" tendency, more than most, and only reluctantly, and at my demand, did he say something to anger me so I could hear my own Beta waves (below), and the hearing of the waves intensified and escalated the anger, I yanked off the electrodes, and steamed off, and John laughed. I soon apologized for my anger and my demand to hear my own beta waves). John has since passed away (?? rumor, from another Sinclair in N. CA., not confirmed), and others more recently say that the sound waves do indeed stimulate mood accordingly. But officially, is it still debatable? have found nothing on the net as to this debate). John Sr and I were good friends and agreed on most things (both of us geniuses), except Astrology. Also note: John invented over 100 patents for the Federal Government, and his first patent (on his own) was the Kick Down Doorstop.

TONE GENERATED ALPHA MU sample (not as reliable) (previous copy was contaminated with some Beta waves, this new copy is much better, but may have a trace of beta overtones, but which seem to resolve to Alpha MU. The Tempo generated Alpha MU wave sample is now better than this (but this tone generated sample is very interesting).
Beta Waves 18 hz (12-19 hz)(cps) - AGITATED brain waves {Tempo: as in rrrrRolling your "R"s, don't do it; or as in a playing card attached to a bicycle wheel, again, don't do it. Conducive to bad behavior, and a threat}. I suggest that you do not experiment on others with Beta Waves, but if you insist on hearing them yourself just copy and paste this link (tone generated) (URL removed) but be aware, it may promote and agitate state, be prepared to follow it up with MU Alpha waves (listed directly above)
Archure Loves GAMMA WAVES.
Gamma Waves 40 cps 26 - 70 hz TONE GENERATED GAMMA WAVES is (as per wikipedia.org Gamma brain waves are related to PERCEPTION and CONSCIOUSNESS in the mind), however, note this Tone Generated sample does not match Wikipedias list, more below). Note: this sample is in favor of discrepancy with Wiki info, in that it sounds like an electrical generation plant (I have been around high voltage operations which sound like this), and electrical generation is 60 Hz (very close to 40 Hz).
HEY, HERES A GOOD ONE FOR YOU! Mu Alpha and Gamma combined, ooooh! Alpha Gamma MU combined, Tone Generated, and Now with Stereophonic Separation of Sound
AUDIO FREQUENCY:
60 hz to 20,000 hz is Audio Frequency (you can hear with your ears)
60 hz is low bass, most musical instruments range in 100 hz to 800 hz, a good sound system should go to at least 5k hz, but to attain a crisp sound, and overtones making a quality clear sound, its nice to have at least 10K or perhaps(?) 20K frequency response from musical speakers. I have kept these low frequency samples at low volume, as low frequency goes right thru walls (keep the bass down for your neighbors please). Speakers with limited frequency range may not be able to play these low frequency samples (try headphones).
April 2010 NEW VERSION with 3 instrument sounds, pan flute, alto sax, fiddle
HEARING RANGE FREQUENCIES in Octave Steps Yes we can hear just a bit further (maybe 2 octave steps up), but not recognizable notes, just sounds
As per Wikipedia (see revised list further below)
C1 32.7 Hz below hearing range of 60 hz to 20,000 hz, not recognizable as a note, or sounds a half step flat to me
C2 65.41 Hz sounds a half step flat to me
C3 130.81 Hz
C4 261.63 Hz
C5 523.25 Hz "Middle C"
C6 1046.50 Hz
C7 2093 Hz
C8 4186 Hz
C9 8372 Hz borderline recognizable as a "C" note, sounds off to me
C10 16,744 Hz not recognizable as a "C" note to me, or sounds very sharp
G10 ? Hz above hearing range of 60 hz to 20,000 hz, not recognizable as a "C" note, or Very Sharp (identifiable as a note, but not identifiable as a "C" note specifically)
But for all I know, there might be limitations to my sound card, or your sound card, perhaps above a certain note they just wing it? who knows? If I had a Frequency Meter I could check and verify my own sound card (I don't have one myself, I used to work at places which did, but we didnt do things like that at work, however, one of the guys used to release a bit of liquid nitrogen for a few laughs (he claimed he was cleaning out the pipes)
INFO CHALLENGE: (I am just in the process of writing this article).
MIDI has over 100 various sound types (flute, strings, horn, guitar, oboe, harpsichord), and SOME OF THE sound modules, are at least 1 octave off, so depending upon what sounds are chosen, this list above may be valid (lead 1 square, or synth bass 2), or, the revised list below may be valid for other modules (lead 2 sawtooth, or synth bass 1), I am still working on this issue
IN SUPPORT OF THE INFO: The list above seems valid, in that the low C1 is not noticeably a “C”, and the low C1 is outside our hearing frequency range (we recognize the pressure, but what “note” (a person with perfect pitch could not differentiate, probably). So that tends to validate the Wikipedia info. THE DEBATE: when I was making a low ALPHA MU NOTE at 10 Hz, I found that MIDI NOTE “F0” was 10 Hz, but according to this data from Wikipedia on MIDI, 10 Hz would be “F-1” (that’s one octave below F0, note the “-“ negative sign, below F0, not “F0”. Previously I have made many Alpha & MU wave samples, not by designating the TONE frequency, but by designation of TEMPO FREQUENCY (I know the Tempo Frequency MIDIs are correct), but the Tempo Frequency MIDIs match in sound to Note Frequency (Cakewalk software) "F0" (not an octave lower at F-1). SEE & HEAR ABOVE in the ALPHA MU section: compare the TEMPO GENERATED and TONE GENERATED samples for comparison, the F0 tone generated, seems to match the Tempo generated samples, which Wiki claims is F-1). Causes: This is due to SOUND MODULES. MIDI can make any note, various sounds, such as Flute, Organ, String, Horn, and some of these sounds may involve Overtones and/or Undertones, which may be one octave off (or possibly more than one octave, especially with some of the Organ and Pad sounds). I am investigating further.
FOLLOW-UP: I have found that the second chart is valid with MIDI module "Lead 2 (sawtooth)", while the first chart (further above) is valid with "Lead 1 (square)". More work needs to be revised on this page, more later.
REVISED LIST: based on comparison of Tempo generated and Tone generated samples.
The 11 notes (midi link above) in order......
C1 16.35
C2 32.7 Hz
C3 65.41 Hz
C4 130.81 Hz
C5 261.63 Hz
C6 523.25 Hz
C7 1046.50 Hz
C8 2093 Hz
C9 4186 Hz
C10 8372 Hz (tone differentiation gets vague)
C11 16,744 Hz
above hearing range of 60 hz to 20,000 hz, not recognizable as a "C" note, or Very Sharp (identifiable as a note, but not identifiable as a "C" note specifically)
(As per a Music Textbook Chart:) Only a few Orchestra Instruments go up to 4186 Hz (piccolo, Glockenspiel, Celesta, and a Harp goes up to 3322 Hz, and a Violin 2636 max. Human vocal range (for written music) is generally 98 Hz to 1046 Hz according to a Music Textbook chart (1970s, I am not certain, the chart may be 1 octave off?, perhaps double each of those frequencies?, will investigate) or according to Wikipedia 512 Hz to 2048 Hz = "Defines human speech intelligibility (horn-like or tinny quality to sound)
Handy Dandy MIDI and CHART for determining what Frequency Range one needs for a sound system (speakers). NOTE: a 5 string bass (with low B) = 61.7 hz, the ideal low for audio frequency (if your bass speakers go that low, and well they should). A regular Bass guitar is 82.4 Hz (low "E"). I would say that 60 Hz to 10,000 Hz would be a very good range, but perhaps a little lower than 60 Hz might be nice (but uncommon, most speaker go down only to 60 Hz, if they go down that low. For a full music system, do start at 60 Hz or lower (not any higher 60 Hz for the lowest range).
SEX: FREQUENCY AT ORGASM
Sex Waves frequency at orgasm is 0.8 sec or (1/T = f) 1.2 cps (cycles per second) X 60 (sec/min) = 72 Metronome. Suitable for sex background music, have sex in time with the music, for better sex. Also hear the same tempo in an actual song "Moon Scorpio" Sexy Music LISTEN: Moon Scorpio
NEW 2010 Sex Waves 2010
NEW 2010 Sex Waves with Tabla and Sitar
Note: 1.2 cps also qualifies as Delta Waves (conducive to sex and deep sleep).
1.14 hz (cps: cycles per second) DEEP SLEEP and/or SEX (Archure believes that the official reference to T=0.8 or 1.2 cps, is actually, more accurately 1.14 cps (derived from theory, not actual testing) or Metronome 73 (but 74 is probably close enough)

HARMONIC THEORY for HARMONY
"Ascending Augmented" Modern Classical HARMONY LISTEN OR ver II
When studying "Atonal Music" and "Modern Classical" at College of Marin, I submitted this idea for a piece to my professor Dr Stan Krasic, in class, and have used it in concert for "crowd control", as it resolves all present Aug 4ths & Dim 5ths (background noises, or any previous oops by the band, intentional or non-intentional), and is made up of Major 3rds, which are harmonious, it works quite well, mellows people out. I also discussed it with members of the Grateful Dead, who liked the idea. If there is a scuffle or argument in the audience, play ascending augmented triads, and it tends to resolve peacefully (quickly)
