The garment is a body instrument that emits musical sounds when the wearer moves in it, as well as triggering a haptic vibration response. It emulates the vibrations that are felt while a musician plays an instrument, and the emotional response that the musician and a performer such as a dervish feels.
The construction of the dress involves a variety of sensors that perform according to how the sound is triggered by the movement of the wearer. These determine the output based on the rotation of the dress using gyroscopes, accelerometers that measure the speed of the dress as it is turning, and flex sensors that trigger sounds when the arms are in certain positions.
The sound design component relies on organic sound samples of the classical Turkish ṭanbūr recorded by a musician and manipulated in computer music design software. This gives the garment a unique edge by functioning as a computer digitized representation of an instrument that is activated by motions of the body. The sounds are triggered using algorithms created in Max Cycling ’74 software. These patches will detect a threshold of movement by the wearer before a sound is triggered.
This according to “Dervish sound dress: Odjevni predmet sa senzorima koji emitiraju zvuk i haptičkim odzivom/The dervish sound dress: A garment using sensors that emit sound and haptic feedback” by Hedy Hurban, an essay included in Muzika–nacija–identitet/Music–nation–identity (Sarajevo: Muzikološko Društvo Federacije Bosne i Hercegovine, 2020).

Skirt dancing, involving the dancer’s graceful manipulation of a full skirt, was a widely popular genre in the U.S. when Loïe Fuller premiered her Serpentine dance in 1892.
Fuller’s costume for this dance involved so much fabric that—combined with atmospheric lighting—it almost completely obscured her human form. By shifting the focus from the dancer to the costume, she added a new level of abstraction to the skirt dance genre, prefiguring many of the innovations of modern dance.
The dance was a huge success and was much imitated, prompting Fuller to sue for copyright infringement; but the judge ruled against her, stating that a dance depicting no story, character, or emotion could not be considered a “dramatic composition” protected by the copyright act.
This according to “Loïe Fuller’s Serpentine dance: A discussion of its origins in skirt dancing and creative reconstruction” by Jody Sperling (Proceedings of the Society for Dance History Scholars XXII  pp. 53–56). Below, a hand-colored 1895 film of an unnamed dancer by the Lumière brothers suggests what Fuller’s performance was like.
On 14 January, which is both New Year’s Day and the Feast of St. Basil according to the old Orthodox calendar, villagers in Bulgaria and Macedonia perform the costumed ceremonial dance known as Сурва (Surva, “unripe year”). Children between 4 and 14 years old participate in the малечка Сурва (small Surva), while adults between 15 and 35 perform in the голема Сурва (big Surva).
On the eve of the event, youths go from house to house collecting wood for the ceremonial bonfire. In the morning the participants choose their roles and don the corresponding masks and sheepskin capes. The stock characters may include a groom, a bride, a devil, a priest, a gypsy, and a dancer with a bear. To the accompaniment of drums and shawms, the dancers parade through the village with abundant comical antics. The ceremony culminates with a spirited dance around the collective bonfire.
This according to “Сурварските обичаи од неколку струмички села” (Old customs performed on New Year’s day in villages of the Strumičko region) by Ivan Kotev, an essay included in Rad XIX kongresa Saveza Udruženja Folklorista Jugoslavije (Skopje: Združenie na Folkloristite na Makedonija, 1977, pp. 207–212).
