Final answer:
Haydn and Mozart followed specific theme orders in their compositions, including the binary and ternary forms.
Step-by-step explanation:
In the Classical period, both Franz Joseph Haydn and Wolfgang Amadeus Mozart followed a specific order when creating themes in their compositions.
One common theme order they utilized was the binary form, which consisted of two contrasting sections labeled A and B. Haydn and Mozart often used this structure in their sonatas, symphonies, and other instrumental compositions.
Another theme order they employed was the ternary form, which had three sections labeled A, B, and A'. The A' section was a repeat of the A section but with slight modifications. This form was commonly used in minuets and scherzos.
