During a typical night’s sleep, the brain’s activity fluctuates. The first three stages of sleep are characterised by three types of brainwaves: alpha waves, theta waves and delta waves.
Delta waves (0.5-4 Hz) signify a state of deep sleep. A binaural beat with a frequency between 4 and 7 Hz, for example, is more likely to align with theta brain waves, promoting sleep and relaxation.

And if you can control your brain waves, they say, you can control ... If you can't focus and your brain is showing lots of theta activity, the logic goes, you'd want to shift up into an alpha ...
