Step 1: Calculate the mean and deviation. uniform, then the standard deviation will be small. indicating that there is a wide variance in the responses, then the standard deviation will be large. meaning. deviation of 1.265 with a mean of 12.
The binary dance movements of the Baroque gave way to the ternary first movements of most Classical period works (sonata, concerto, chamber music, symphony) which comprised three parts: exposition (A) development (B) and recapitulation (A).
Sonata form is by far the most important of these forms, and one that continued to evolve throughout the Classical period. Although Baroque composers also wrote pieces called sonatas, the Classical sonata was quite different. One of the most important developments of the Classical period is the growth of the public concert. Although the aristocracy would continue to play a significant role in musical life, it was now possible for composers to survive without being the employee of one person or family.
