CONDUCTORS OF THE WORLD TAKE NOTE !

BEFORE THE INVENTION OF THE TUNING FORK AROUND 1850 ALL INSTRUMENTS WERE TUNED A HALF STEP LOWER.THAT MEANS OUR A{NOTE} WOULD HAVE BEEN A-SHARP TO BEETHOVEN.SO NOW WHEN ANY ORCHESTRA
PLAYS BEETHOVEN OR ANY COMPOSERS MUSIC THAT WAS WRITTEN BEFORE 1850
THEY ARE NOT PLAYING IT AS THE COMPOSER ORIGINALLY MEANT IT TO BE HEARD.
