Answer:
A. Tongali
Explanation:
In the Philippines, the nose flute (pitung ilong in Tagalog), or the kalaleng of the northern Bontok people (tongali among the Kalinga people), is played with the extreme forward edge of the right or left nostril. Because the kalaleng is long and has a narrow internal diameter, it is possible to play different harmonics through overblowing—even with the rather weak airflow from one nostril. Thus, this nose flute can play notes in a range of two and a half octaves. Finger holes in the side of the bamboo tube change the operating length, giving various scales. Players plug the other nostril to increase the force of their breath through the flute.
