Final answer:
Song duels, while a prominent tradition in Greenland, are not exclusive to it; similar practices are found among the Inuit of Canada and various other cultures worldwide.
Step-by-step explanation:
The statement that song duels are only performed in Greenland is false. Song duels, also known as piseq, are indeed a significant cultural tradition in Greenland, particularly among the Inuit people, where they serve as a non-violent way to settle disputes. However, the concept of singing or poetry contests can be found in various cultures around the world. For instance, the Inuit of Canada also practice this tradition, and similar types of verbal dueling can be seen in other indigenous cultures. Additionally, poetic and musical competitions exist in various forms globally, whether in traditional or contemporary settings.
