Contrasting Moods in Classical Style

The classic era began to include contrasting moods within a single theme rather than expressing a unique affection. The contrast in counter melodies and themes with frequent changes from long notes to shorter notes, syncopations, gradual dynamics, unpredicted pauses, and a variety of keys would change gradually, or suddenly to express a particular emotion the composer wants to project. The example is a fragment from the Flute Concerto No.1 in G (K. 313) by Wolfgang Amadeus Mozart, which represents some of these characteristics.
