Nafir Nafsir, like the Bushehr trumpet instrument, is made of deer antlers, mountain goats, and cows, but unfortunately, the use of this instrument has become obsolete today. Appearance: Nafir, also known as Nafir horn or Nafir horn, is a twisted hollow horn that has a hole in the area near the tip of the horn for blowing. But in other parts of the body there is no hole to change the sound. Executive technique: Although the structure is very simple, at the same time it takes a lot of pressure to make it sound. The pitch of the instrument depends on the length and diameter of the horn tube. Nafir sound is intermittent and the breathing technique is not used for playing. Also, the way it is played, despite not having a embouchure, is like wind instruments with a embouchure. The instrument's sound follows harmonic rules, and in addition to the base sound, it is possible to create fifth, fourth, and octave sounds. Administration: In the past, it has been used to keep wild animals away from farms, to announce attendance and messaging, as well as Qalandari and Dervish rituals. In the Dervish religion, especially the Khaksar dynasty, the Dervishes, who were constantly traveling and homless, had the following requirements: Nafir, Kashkul, Montasha, Zain ax, Zunar, hat, whale saw, shroud, hat string, contentment stone and surrender stone. Their dervishes used Nafir to inform of the presence of the dervishes and sometimes to complain to God. Naftir has also been used in the tin houses and in the battlefield.
