All six well known frequencies as one.

Would advise only trying these after a bit of exposure to the single frequencies. You might notice it is closer to the classic chanting noises many make.

After that if you still want to go a step further, again after practice and making sure your not getting headaches etc. This is all a healing process remember, move at your own pace.

Here you can play many at once through different browser windows. The most i've run so far is 17, all those on the main page at once. I have had a lot of experience with them, and while relaxed in meditation, had a headrush sitting up.

Again take it a step at a time, try all six for at least a few days first individually. I'd advise longer but time is speeding up, so all bets are off :)

Deepest Energies to you all,
