physical reaction to music is the same as how a person would to a certain sonic stimulation/situation or aural sensation. people will dance to techno, disco, funk, samba/bossanova/calipso/cha-cha and rock & roll because of the beat... headbanging, moshing at slamdancing naman ang reaction sa metal (mapa-heavy, speed, grind o death pa yan) , hardcore/punk/emo/ska (new & old skool a like) and grunge because of the energy that comes out of the music... jazz naman mostly taken sitting down therefore illiciting toe or foot taps, finger snaps and a little head bobbing. R&B and hiphop naman ang dahilan kung bakit maraming nabubuntis ng maaga... as for indierock and indiepop is a breeding ground for unconventional body movements and pa-cute dancelike gestures... sa shoegaze naman (sama na natin ang noisepop/dreampop/goth/ethereal/darkwave/softcore/60's psychedelia/ambient-trance-chill-out) iba... sa loob ang epekto to the point that when you're hit hard, it puts you in a motionless state of being most of the time. the sound that these musical forms create plays with the mind...

oo nga pala... wala lang!!! happy INDIEpendence day to everyall of you!!!
