> Both sessions used the same music (movie soundtracks) but tuned to 440 Hz on one day and 432 Hz on the other. Each session consisted of 20 min' listening.
Keep in mind that 1) 100% of study participants would have grown up listening to a particular tuning reference (I think Italy is A440) and 2) to change music from A440 to A432 you either have to slow it down a proportional amount or use an algorithm to chop it into its frequencies and reconstitute it.
