Dwarven Hand Dancing

"Dwaven hand dancing," as it is referred to in Common, is a very, very old style of dance traditionally accompanied by a very specific aesthetic.
It is performed in groups of at least four dwarves, though hand dancing troupes can become quite large, especially in the city. The “look” of the dancers is very specific, featuring a dark brown, close-cut style of beard, dramatic dark eyeshadow, and a pale-colored headscarf. Dancers were once required to grow their nails out, but in modern times, it's okay to wear false nails instead, as long as they’re a natural or neutral color. Part of the goal is for the dancers to look as similar as possible (much like with modern-day cheerleaders), so dedicated dwarves will dye or color their beards and eyebrows right shade of brown for the performance. Alternatively, they will shave and apply an expertly-crafted costume beard, or draw in their eyebrows with makeup. Sometimes the dancers wear jewelry, but never on their hands or wrists, as they need their fingers completely unimpeded to complete some of the traditional moves of the dance.
The dance itself resembles a mix of Kuchipudi and tutting. As one might guess, hand dancing is primarily focused on showing off the dexterity and form of the dancer's hands, combining twisting and sweeping arm and shoulder movements with quick, controlled changes in their fingers. The dance is performed to a bouncing, repetitive beat. Hand dancing has many specific, named moves, and each subgroup of dwarves has different rules about the order in which these moves should be strung together.
Beginner dancers are often surprised to learn just how much full-body control is needed to complete the moves, and it is widely considered to be a difficult dance to truly master. Professional dancers are at a higher risk for repetitive stress injuries in their hands and wrists, and many have developed long rituals for hand-care. The dance culture is strict when it comes to form, but very inclusive when it comes to participants, and recent decades have seen more acceptance of forms adapted for those with prosthetic hands and arms.
Origins of the dance are said to be from a time long ago, when smaller (or more effeminate-looking) dwarves were pressured to stay in their homes and out of the mining and crafting industries, under the misguided belief that they were “too delicate” for that kind of work. The dance developed first as a pastime, but eventually turned into a peaceful form of protest. To this day, it lives on as a semi-sacred celebration of the skilled hands of all dwarves.
Because of similar twisting movements seen in both, ignorant tourists visiting Lockhinge will sometimes mistake hand dancing for forms of tiefling traditional dance and vice-versa, which deeply offends both parties. Some have theorized that the tiefling dances seen in Lockhinge may have borrowed a few moves from dwarven hand dancing when tieflings initially settled in the Greymantle area, but modern day dancers all agree that comparing the two is an apples to oranges situation.
