Step-by-step explanation:
Possente Spirto is an example of a(n) aria, whereby a character expresses how he/she feels with elaborate, ornate, and melismatic singing.
This form can be found in early operas and is known for its expressive and often virtuosic vocal lines that convey the emotions and thoughts of the character. In contrast to recitative, which is more speech-like and moves the plot or action forward, an aria is more musical and focuses on showcasing the singer's voice and the melody.
