In our last episode we talked about beat induction and rhythmic entrainment, this is what causes us to pick up the beat around us and tap our feet, even if we aren’t consciously doing it. I mentioned at the very end that there are cutting edge music therapy techniques that use entrainment as a means to treat neuro-biological disorders. The idea is to use outside auditory stimulus, drones, drumming and the like, to change the mental state of the listener.
