Another headcanon since I’m on a roll, this time it’s about traditional dwarvish dances. This is headcanon is heavily inspired by the Dhikr (see the video, in particular after the 15:00), as well as Thorin’s awkward little dance in Rivendell (you know the one).
Dwarvish dance is a lot about making noise and throwing your weight around. Dwarvish “stomp” as I call it, is all about dancing together as an addition to the music. It will often be accompanied by rythmic shouting or singing. In dwarven eyes, if you don’t dance until the walls rattle and the mugs on the table fly all over the place then the party is kind of... lame? This is ESPECIALLY true during weddings, where dwarves tend to get very drunk and dance until they faint or fall asleep (it’s considered rude to the couple to not dance until you’re dead tired).
Traditional dwarvish dancers will wear very heavy armour and stones so that they may artificially increase their weight, and thus increase the intensity of their stomping. This is why dwarvish dancers are very known for their muscles (where their legs and core tend to be particularly well developed). Dwarf dancers will according to custom also tattoo their entire legs to show their profession which is highly regarded among dwarves.
“Dwarvish stomp” is also commonly used in war. Dwarvish armies will dance in order to intimidate opposing armies, making the sound of their stomping echo through the mountains which they inhabit. This will often make their army appear larger than it actually is and also signify the physical prowess of the dwarven armies. This tactic is commonly used by Broadbeam armies (who are in fact known for their intimidating presence on the battlefield).
