Dirmil Sipsisi

Dirmil Sipsisi is a traditional wind instrument unique to the Altınyayla district of Burdur, made from reeds known locally as "demir kargı". This instrument has distinctive features including a mouthpiece made of a thinner reed, with five holes on the top and one on the bottom. The mouthpiece section is also locally referred to as "cukcuk".

Owing to its physical structure, the Dirmil Sipsisi can produce eight distinct tones in sequence. Depending on the skill of the craftsman and the pressure applied, this number can increase up to twelve tones. Local folk songs are typically performed using the Dirmil Sipsisi. Another important feature of the instrument is the ring used both to add decorative patterns and to prevent the reed from cracking, which is made from the bark of the "ala eğri ağacı" tree native to the region.

The main materials used in the production of the Dirmil Sipsisi are as follows:

• 5 mm wide iron rod (used for drilling holes in the reed)
• Durable cotton thread (10 cm)
• Cleaning rod (20 cm)
• Hard reed growing in marshlands (demir kargı)
• Bark of the ala eğri ağacı tree

The production process begins by cutting a reed to approximately 17 cm in length. Using a heated iron rod, the first hole is drilled 3 cm below the top end, followed by four additional holes spaced 2.5 cm apart. The bottom hole is drilled 2 cm above the tip using the same method. After drilling, the interior of the reed is cleaned with the cleaning rod.

Next, rings made from ala eğri ağacı bark are inserted: two at a distance of 2.5 cm between the first and second holes, two at 2 cm intervals between the remaining holes, and one at 3 cm between the fifth hole and the end of the instrument. These rings serve both to decorate the instrument and to prevent the reed from cracking.

The mouthpiece is approximately 4 cm long and has a diameter of 0.3–0.5 mm. It is cut horizontally to a length of 3 cm at the top to enable sound production through vibration. After cleaning, the mouthpiece is fitted into the main body and wrapped at its base with durable cotton thread. This process secures the tuning and prevents the vibrating section from breaking.
