Note Frequencies

As a bit of a music freak and as hypnotism weirdo I like to think about the frequencies of the different notes. HUH?! Well each note vibrates at a certain frequency. That's how it works. Music just like everything else in our universe (seemingly) can be explained mathmatically.

E5 is 659 Hz for example. this is important when when trying to create brainwave entrainment through binary beats.

Generally speaking you can create a good "beat" for hypnosis with a difference of 10 hz between the tone in the left ear and the tone in the right ear.

So if I use an E5 note in the left ear at 659 I'd want to use a tone of 669 hz in the right ear. Since an F5 is 698 Hz - which is 39 Hz higher this tone would basically be just short of 1/4th of a note higher.

I think, but I'm not sure, that it's important for the two tones to not be discernable from each other in pitch. Considering this it should be better to use higher notes than lower... I'll use an example for what I am talking about... A C1 is 32.7 Hz... so would take that up to 42.7 Hz to create the 10 Hz binary beat. The problem is that a 42.7 lands you somewhere between an E and an F note! This would clearly be heard as an entirely different note, correct?

I feel that I must do some more real world research with these ideas.

I *may* get back to you with some of my findings...

If you want to hear a previous experiment I did with binary beats check out my "radio play" entry. There's a lot going on there but included in all of that is a binary beat of 10 Hz to help create the feeling of otherwordliness. Actually if I remember correctly it's a beat oscillating between 5 Hz and 10 Hz...
