Alpha pattern: Binaural beats in the alpha pattern are set at a frequency of between 8 and 13 Hz, which may encourage relaxation.

Beta pattern: Binaural beats in the beta pattern are set at a frequency of between 14 Hz and 100 Hz, which may help promote concentration and alertness. However, this frequency can also increase anxiety at the higher end of the frequency range.

Delta patterns: Binaural beats in the delta pattern are set at a frequency of between 0.1 and 4 Hz, which is associated with dreamless sleep.

Theta patterns: Binaural beats in the theta pattern are set at a frequency of between 4 and 8 Hz, which is associated with sleep in the rapid eye movement or REM phase, meditation, and creativity.

Blind tests (to avoid any kind of bias) where the participant did not know which frequencies would come for what purposes and at which time there were frequency changes.

The volunteer listened to alpha and gamma frequencies, with and without interference from two songs. A quiet (Comming Back to Life, Pinkfloyd), and a bustling (Hearts on Fire, Hammerfall).

The binaural beats proved effective in altering the conscious state of the volunteer inducing their respective states, even with the influence of songs that would counteract the state in question.

As the sample was of only 1 volunteer, we can, to do a research with more participants to guarantee all the premises of the scientific method. But since there is material to support the theory and we have seen evidence in this preliminary test, We are convinced of the efficacy, not as a complete alteration of mood, but as something that has the power to induce people to moods.
