The first movement of a symphony can be a fast movement, often in sonata form. The second movement can be a slow movement. The third movement can be a minuet or scherzo and a trio. The fourth movement may be called “Finale”; it can be in Rondo form or sonata form or a combination of these. There are lots of different ways of writing a symphony, but this is the pattern that was used by Joseph Haydn who is known as the “Father of the Symphony”, and many composers since have used his pattern of movements for their symphonies.
