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.
Ludwig van Beethoven (16 December 1770 - 26 March 1827) was a German composer and pianist. He was a crucial figure in the transitional period between the Classical and Romantic eras in Western classical music, and remains one of the most respected and influential composers of all time. Born in Bonn, then in the Electorate of Cologne (now in modern-day Germany), he moved to Vienna in his early twenties and settled there, studying with Joseph Haydn and quickly gaining a reputation as a virtuoso pianist.
