why brain does that when we listen to a song

[nicholasman206]

hi guys

i just joined in and the only reason is i really need to know the answer :

why when we listen to a song or even a sentence or a word... for many times (10-20 at least)

then... these things happen:

1- we remember it during day even when we are not think of it... "ear worm"

2- we can recognize and remember it after even years... a song ive heard when i was 7... i can remember even at age 60 !

anyone can help me with that and know the science reason and terms about it so i can search more in net ?

Our brains and our bodies operate on rhythms. When we were in the womb, all we knew were rhythms. When our ancestors were in the oceans, all they knew were rhythms. Our bodily functions... the beat of our heart, the expansion of our lungs, the blink of our eyes, the firing of our cells are all each themselves little biological symphonies made up of numerous orchestral instruments. Sometimes, when we listen to music, it is resonant, and some melodies resonate more deeply and more completely than others.
