Which composer is associated with standardizing the four-movement symphony and introducing Mannheim's energetic style?

• A. Sammartini
• B. Haydn
• C. Stamitz
• D. Mozart

Answer: (C)

Understanding how the symphony evolved in form and orchestral drama in the mid-18th century is what this question is testing. Stamitz, leading the Mannheim school, was pivotal in making the four-movement layout a standard: a brisk first movement, a slower contrasting second, a minuet or scherzo in the third position, and a lively finale. Along with that formal blueprint came a distinctly energetic style—bold dynamic contrasts, rapid crescendos that push the music forward (the so-called Mannheim motion), and a keen sense of orchestral color and momentum. These traits defined Mannheim and became a template later composers like Haydn and Mozart would refine, while Sammartini contributed important early symphonic work but not the Mannheim-style energy.
