Answer:
Option A
Explanation:
A thematic transition also recognized as thematic development or transformation refers to the musical techniques where a leitmotif or pattern is formed through the use of possible combination (notation or rotation, reversal, and retrograde), increase, decrease, and separation to change the subject.
Throughout every musical composition a simple concept is repeated, but it needs to undergo fundamental changes and conceals, and is presented to the public in many conflicting positions. Furthermore, the modifications of this framework will still fulfill the function of "connection within diversity," which in the traditional sonata was the structural task of a sonata.
