Gilan trumpet: Another group of wind instruments, are absolute wind instruments with a cup-like mouthpiece, similar to a cup that has different uses in different parts of Iran. Gilan tumpet is considered to be the tallest wind instrument in Iran and is one of the oldest and most primitive wind instruments in different parts of Iran. This instrument is completely compatible with the geographical area of ​​Gilan in terms of material and construction Appearance: Gilan's trumpet consists of a long sound tube that has an mouthpiece for blowing air at the beginning of the instrument, and the end of which is bent like a cane. This sound tube is made of blue straw, which is known as (tube azite) or (Garloleh). The length of this reed is between two to more than four meters, which is wrapped around the main pipe in order to make it stronger than long cut reeds. The cane-shaped end of the tube is the place where the sound comes out and is made of a kind of pumpkin called a (kaduni). The part of the Gol Karney made of pumpkin, is the interface between the Kaduni and the Karloleh. The mouthpiece part is called the Karney Pisheh, which is made of straw or wood and is in the shape of a spoon. Executive technique: Due to the longevity of the instrument and the unique structure of the mouth, more force is needed to make it sound. Also, due to the lack of holes in the sound pipe, the rules of harmonic sounds have been used to produce sound; So, you can create octave, fifth and fourth sounds in addition to the basic sound of this instrument. Due to the length of the instrument, the breach- back technique cannot be used to play, and the duration of the player's unbearable weight bearing on the player's hand for a long time is short. Trumpet’s voice is muffled, and a combination of several trumpets creates a random homophony. administration: In the past, it was used for news coverage, but today it is used in Muharram mourning ceremonies and sometimes taziyeh. The trumpet is played as a group, with one person leading the group and leading the musicians. The group leader (Sarkarnachi) and the rest of the musicians are called (Vagir). Musicians have poems in their minds and perform a few rhymes with the rhythm of the poem. This is called trumpet reading, and musicians play the trumpet whlile standing and moving.
