Assuming the teacher means zero Fahrenheit, the same temperature is minus 17.7 degrees Celsius. If the zero is Celsius, changing it to Fahrenheit gives you 32 degrees. But, the teacher said it's going to be twice as cold, and that is something completely different and more complicated.
Beethoven is considered the transitional figure between Classical composers Haydn and Mozart on the one hand, and the Romantics on the other. His innovations included his construction of his Sixth Symphony (The Pastoral) as program music and his expansion of the quartet, concerto, sonata, and symphony forms.
That question made my day.LOL I'm sorry I just even if you are young...you should know that was in the 1800's. Ludwig van Beethoven was born in Germany in 1770 and died in 1827 at the age of 56. I have a friend who likes to visit cemeteries . She went to a cave in Germany and as she entered the dar depths she heard great music played on an organ . Rounding a bend there sat Beethoven , playing weird sounding music unheard before . Approaching him she asked ,  Are you not dead and what is that weird music you are playing..
