A440 or A4, which has a frequency of 440 Hz, is the musical note A above middle C and serves as a general tuning standard for musical pitch.
Prior to the standardization on 440 Hz, many countries and organizations followed the Austrian government's 1885 recommendation of 435 Hz, which had also been the French standard since the 1860s. The American music industry reached an informal standard of 440 Hz in 1926, and some began using it in instrument manufacturing. In 1936 the American Standards Association recommended that the A above middle C be tuned to 440 Hz. This standard was taken up by the International Organization for Standardization in 1955 (reaffirmed by them in 1975) as ISO 16. Although not universally accepted, since then it has served as the audio frequency reference for the calibration of acoustic equipment and the tuning of pianos, violins, and other musical instruments.
It is designated A4 in scientific pitch notation because it occurs in the octave that starts with the fourth C key on a standard 88-key piano keyboard. On MIDI, it is note 69.
Year 440 (CDXL) was a leap year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Valentinianus and Anatolius (or, less frequently, year 1193 Ab urbe condita). The denomination 440 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

This is a song called "A" which is based on the german standard of the concert pitch. The concert pitch is according to the german standart exactly 440 Hz which is used to tune instruments which using this standart note system. The song is also very long because I am pretty sure that you will like it so much that you can't get enough from it,so you don't have to push that often your replay button. Enjoy!!!

This video is a cymatic version of Sound Frequencies in Water: A=440 Hz vs. A=432 Hz. It has been said that music tuned in A=432 Hz is more beautiful and harmonious to the ears and induces a more inward experience where music tuned in A=440 Hz is more outward, mental experience which is projected outwards. I am sure you have already seeing the following still photos of how the A=440 Hz vs A=432 Hz looks like. They have been circulating the net for some time. Well I thought it will be cool to generate them using my cymatoscope…and so I did…in real time! It is said that “a picture is worth a thousand words”...well I would add that "a video is a perfect shot of reality..." Conclusion: Don't let yourself be fooled by images you have been shown on the net. Investigate the truth yourself! This i...
There's been a debate floating around about whether instruments sound better tuned to 440 Hz or 432 Hz. While 440 is the standard tuning (and what the vast majority of songs today are tuned to) there are arguments that 432 is a better, fuller, more natural tuning. There are even extreme theories that 432 has healing properties and todays mainstream 440 usage came about from the Nazis, Illuminati, etc. because it agitates people and causes them to be aggressive. This video allows you to test yourself to see if you like 440 Hz or 432 Hz better. You won't know which sample is which. Listen to each and see if you like one better than the other or if one feels better to you than the other and draw your own conclusions. Key Change: A lot of people come into this video with their mind already...
Here it is you guys! You be the Judge and let's share this with everybody you know, and let's discuss this Huge Important topic! What I did was record 3 different short rhythms in 432 Hz tuning and then 440 Hz tuning. The only thing changed in each Case was the tuning of the guitar. Same guitar, same strings, same tuner, same recording program, same guitar pick, same microphone, and same Digital USB Mixer. Each frequency has a distinct sound for sure, but learning the history of each one was Shocking to say the least. Please feel free to Google more about the difference and where each one came from. There is no doubt in my mind than Human manipulation has always been around, but this is huge. We all listen to music everyday, and learning the effects of the frequency we play and listen t...
The conspiracy of tuning musical instruments has centered around the 440 hz debate. This video will endeavor to spark an important dialogue concerning the medium that influences our souls: music. ********* Three years, 31552 views and 117 comments later I am glad to answer some questions and comments*********** 1) The original "Three Little Birds" recording was not played or recorded in 432 hz. I simply put the song through an application that lowered its frequency. The same goes for the opening song by Giannis Parios entitled "Sala Sala Dimotika". They are in fact recorded in 440 hz. 2) To my knowledge the only song in the contemporary era that was originally recorded in 432 hz is Reflekt's "Need To Feel Loved". Listen to this track and you will immediately feel what I was trying to get t...

Delta Waves are associated with the state of consciousness of very deep sleepers. I designed this particular Binaural Beat to output a high range tone of 440Hz with a pitch difference of 2Hz from one ear to the other. When played through stereo headphones, the slight difference in frequencies entrains the brain's Delta Wave frequency production. This type of audio stimulus has been used to induce the same state of consciousness as very deep sleepers. Let me know in the comments what effect this stimuli has on you!
