Listen: Musical Note Perception Can Depend on Culture
"Music music but what shapes our perception of music to candidates are the limits of the human brain and the exposure. We've already had to music during our lives. If we only test participants with expense with best music than we'd really can't know whether the speeches come from the experience or from the biological constraints psychologists noory Jacoby of the max-planck-institute for empirical aesthetics during the past few years he and his colleagues have visited a remote area of Bolivia took investigate this question so we traveled there by taking canoe ride or it can Cessna plane or a couple of hours track to communities. Don't have running water orange. The CIMINI are an indigenous people who live in the Amazon Basin we specifically recruited participant from the believe in Amazon because this this participant had relatively little exposure to music for example octaves are a staple of western music but Jimani musical instruments don't feature them as an acoustical go phenomenon. An octave is defined as the interval in which the vibrational frequency of the bottom note is half that of the top note. They're considered the same note inactive apart for example Middle C. N. Nine High C. for the study she money participants pence were asked to listen to simple melodies and sing them back to the researchers. This exercise revealed that the money don't perceive tones that are knocked of apart as the same note on the other hand participants from the US did recognize octaves other musically trained Westerners were better at it than those with no musical training ansel Hansel what is exciting years highlights the importance of experience and exposure on the mind the researchers in the journal current biology in an earlier study Jacoby Bubis colleague Josh Mcdermott and his team from mit found that the chimney don't find an unpleasant to hear notes sight-seeing f sharp played together but there are distant Combo. That's particularly grading too many western years. Despite the evidence that experience influences pitch perception biology college is also a factor. Jacoby says the new study also revealed the both Westerners and the Toumani have trouble distinguishing between really high notes above four thousand thousand Hertz even though human hearing goes all the way up to twenty thousand Hertz and that may be because no matter where we're from we hit the limits of our brains before we reached the limits of our ears.
