<p>A method includes adding, by a computing device, a brain wave pattern having a first frequency to a music track having a first decibel level at or above a threshold of hearing by mixing the brain wave pattern under the music track at a second decibel level less than the first decibel level, wherein the second decibel level is at or below the threshold of hearing, adding, by the computing device, a repetitive chant having a second frequency to the music track, by mixing the repetitive chant under the music track at a third decibel level less than the first decibel level, wherein the third decibel level is at or below the threshold of hearing, and recording, by the computing device, the music track with the brain wave pattern and the repetitive chant to a computer-readable medium.</p> |
