If you keep re-playing the video, the sounds appear to keep getting higher each time.

Until the fifth time, I realized it was playing BOTH the high and original note.

thaaat definitely didnt do anything

I`m very involved in orchestral and symphonic music, so I merely heard the same thing over and over again

If you wait about two seconds after it stops it doesn`t work.

They`ve got lots of auditory illusions and binaural recordings like this on:

I didn`t feel like re-starting it 5 times.

Dang it every time I go to watch a video on the computer I`m expecting something to jump out & go "RAWWWRR."
The internet has made me so paranoid.

all they did was play harmonic notes, and you`re brain just picked up on the highest harmonic note when you replay it.

Am I the only weirdo who heard the same thing every time - just the same harmonics played over and over?!

This kinda thing only works with perfect tuning..if a piano is perfectly in tune it will work but if it isn`t you wont hear the overtones, which are very important to the effect. Also a Music Major...

Also this effect tends not to work for those who played bass instruments like String bass, Trombone and Tuba.

You know a better idea would be to not tell anyone that you have to replay it, and just repeat the same tones over again making it twice as long. And then at the end of the video point out that the 2nd set of notes was the same as the first.

I still heard it "change," but I understood the idea of overtones before that.

If you listen for it, you can continue to hear the lowest overtone every time.

I realized that while half-way through the video, if you put it back to the beginning it seems to not work. I played about 3/4 of the video and put it back near the beginning it seemed to restart.

to those who point it out, you don`t need to... if you say it was "simple", then don`t point out the obvious. any1 with any music knowledge knows, those without music knowledge won`t really care

really doesnt work for me. like the first note after you play it again sounded harder then my mind knows its just going back up the scale again. stupid music skills

Trumple, its been explained like seven times now.

Its as simple as one of those optical illusions with the elephant with six legs, or anything like that, its just aural instead of optical.

Basically, your brain knows what it wants tod o, and it tries to do it, and unless you`ve been trained to listen for pitches in chords and harmonies (like any of us musicians have been), then you probably will be fooled...

It didn`t work for me.
But I play the piano almost constantly, so I`m a good judge of pitch.

Errm... This is kind of a dumb trick.

Each pitch is always played in several octaves at once, so when you start the video over, you are focusing on the next octave up in that fundamental pitch. Sorry, music major here.... :-[

kaseyface said exactly what I was going to. Each "note" had more then one tone, so on the first one you hear the highest one, making the whole scale sound higher.

Very clever! But after the third time, about half way in, it went back to normal.

EnlistedOne:
It`s good to know I wasn`t the only one who anticipated the lowest harmonic to play upon repeat. My friend thought I was a freak for not hearing how the pitch "obviously went up."
I`m glad all those music lessons were good for something... I think.

I noticed how it worked also. There are several notes being played, all on different octaves. After the notes are played (notice there are 12 of them, one for every note), we restart it, and then we hear the higher octave as it keeps going.

Pretty neat stuff. I fell for it.

it didn`t work for me at all. i think it`s because i`m so deeply intwined in my music that i was able to aurally judge the tone even though it was designed to trick me. it was a pretty cool little test though. it`s all about the brain working with the sounds it`s given versus common pattern. :)
