Classical music genre

Classical music genre is a broad umbrella term

to refer to orchestral/instrumental music from

Western Europe appearing from the middle ages

and its modern imitations. Aesthetics of

Classical music evoke the values of European aristocracy

(who sponsored the music), traditional/conservative mindset

of successful composers and religio-cultural constraints of Western Europe. Classical music is not synonymous with western european 'folk music' which is considered a different cultural subtext in which the refined and systematic 'art music' evolved.

Classical music is imitated for the grandiose feelings of

awe and pathos which are triggering a fear response due

low frequency harmonics creating a monaural/binaural beat pattern

in the low-mid theta waves in the human brain.

Classical music is tuned to 440hz by convention though the original compositions had a much wider range and diversity of tuning(some of which, like 432hz tuning is currently popular as alternative).
