Neuroscience can curate music based on your brainwaves, not your music taste

The frequency at which your brain resonates defines your state of mind.

Need to chill out? Try alpha activity.

Want a pre-workout pep-up? Pop on some beta waves.

Our brains are sophisticated electrical factories, powered by more than 100 billion nerve cells. By synchronizing our biological rhythm to environmental cues like music, you will be able to plug in your headphones, lean back in your chair, and relax to a playlist so synchronized with your brain’s chemistry that it increases your focus, sleep quality, and even fights anxiety.

Companies and composers have begun using software to make music customized to your brainwaves.

“Eduardo Miranda is a musician and composer who is best known for his liberal use of the electroencephalogram (EEG) machine to create complex string arrangements. For his next act, he is using brainwave-imaging software to change how he creates his music. Specialists have long used EEGs to diagnose and study epilepsy, sleep disorders, and other medical issues, but Miranda is using the technology to measure how rhythm affects brain activity.”

In one recent experiment, Miranda studied three groups of subjects with the EEG’s small metal disks and electrodes attached to their scalps.

  • Group A, Miranda tried to inspire happiness and energy by having subjects listen to fast-paced music 
  • Group B, he tried to divine sadness with slower tempo, gloomy tunes
  • Group C, a control group, listeners heard neutral music intended to sustain their current mood.

The EEG recordings showed their brainwaves all became synchronized around the auditory rhythm they were listening to. They also reported a change in mood after listening to each composition.

“By connecting how the brain synchronizes its electrical frequencies with the rhythm of music, Miranda posits that certain beats coerce alpha and beta waves—two of the six types of brain waves—into a desired state. He says that soon, with a few alterations, companies could use his research to create a product that empowers consumers to take greater control over their emotional state. “I’m very optimistic in about five or six years time we will have this thing working mainstream,” Miranda says.”

Other companies are trying a different tact entirely. On website, listeners plug in their headphones and listen to songs that activate their alpha and beta waves in order to relax, focus, meditate, nap, or sleep. Launched in 2016, users review’s options, click on their desired mood, and then sit back and listen to tracks designed to produce that state.

Each track is timed to the millisecond to the rhythms required to stimulate and coerce brainwaves into the desired state. Songs are composed by thousands of bots each assigned a character—from a raindrop to a cymbal clash—that arrange themselves to create a stanza. When patterns emerge in the first several dozen measures, the bots arrange themselves to mimic those stanzas, which produces a complex composition. Each track is timed to the millisecond to the rhythms required to stimulate and coerce brainwaves into the desired state.”

“After several minutes, asks listeners to rate its effectiveness. Since brainwave frequency varies slightly from one person to the next, the algorithm continues to modify the tracks played until the user rates their experience as “very effective.”

“Recently, producers have reached out to to learn how to create music more biologically in key with their target audience. Artists are looking for ways to sync their songs to user brainwaves, says founder Junaid Kalmadi.”

  1. This is both exciting in its potential application for helping people be productive or to lift their moods and alter behavior for the better, but it’s also terrifying in its potential for abuse.
    I can see how this might even be used to correct brain diseases one day – and that would be a very good thing.
    I guess the same could be said for chocolate.
