Another topic that we are looking at with music perception is Individual Variation.
The definition we used earlier was that music perception refers to the cognitive and sensory processes that allow us to interpret and organize musical sounds. It involves processes in both the brain (for organizing and analyzing auditory information) and the ear (the actual process of hearing).
One famous example of Individual Variation is "Yanny or Laurel?" which was an audio snippet that was similar to the black/blue vs white/gold dress debate. The many millions of people that have listened to the clip insist that they hear one and don't understand how people can hear the other, but it's as simple as individual variation in auditory listening.
However, this perception most likely changes for each individual depending on things like their musical preference or differences in musical ability. Someone who has synesthesia also probably perceives music differently because of the associations their brain creates with auditory stimulation. In addition, there are a number of auditory disabilities, such as being deaf or having a cochlear implant, which can influence how people hear music.
