“Musicians sort of knew this already—that the emotional center is not the technical center, that funky grooves are not square, and what sounds like a simple beat can either be sensuous or simply a metronomic timekeeper, depending on the player.”

PowerPoint may not be of any use for you in a presentation, but it may liberate you in another way, an artistic way. Who knows. -David Byrne

when you meditate, you are focusing on something, whether it’s a candle flame or your breath going in or out, or a mantra or a prayer. When you focus like that, the electrical patterns in your brain slow down and relax, and the amplitude of your brain-waves generally stabilizes in the alpha wave range. But it turns out that you don’t need to be a trained monk or meditate for weeks on end to be able to achieve this state of alpha brain wave relaxation. Instead, you can use a concept called “brainwave entrainment” to get the same effect. Brainwave entrainment is any method that causes your brainwave frequencies to fall into step with a specific frequency. It’s based on the concept that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus (such as music, or sound). The type of sound frequencies that are typically used in brainwave entrainment are called “binaural” beats. The way that these work is that two tones close in frequency generate a beat frequency at the difference of the frequencies. I know this sounds complicated, but it’s pretty simple to understand when you think about it. For example, a 495 Hz audio tone and 505 Hz audio tone (whether overlaid in music or in a sound frequency) will produce a 10 Hz beat, roughly in the middle of the alpha brain wave range.
