Classical Period Characteristics

The Viennese Classical Style

• The Viennese Classical style, which emerged in the late 18th century, is characterized by clarity, balance, and formal structure
• Emphasis on melody, with clear phrases and cadences, often in a question-and-answer format
• Use of homophonic texture, with a clear melody supported by accompaniment
• Expansion of the orchestra to include wind instruments and timpani, allowing for greater tonal variety and dynamic contrast

Patronage and the Changing Role of the Composer

• The patronage system, in which wealthy aristocrats or institutions employed composers, was prevalent during the Classical period
• Composers like Haydn and Mozart worked under the patronage system, composing music for their employers' private concerts and events
