I want to know the answer to the following question:
How many movements are symphonies written in the Classical period usually divided into?
All the background I'm provided with is that "For instance, symphonies written during the Classical period are usually divided into four movements: (1) an opening Allegro in sonata form, (2) a slow movement, (3) a minuet or scherzo, and (4) a final Allegro.". Is that enough to answer the question?
Answer: yes
