This skill is mainly used for the purpose of revitalising an adjacent unit that has already moved, allowing them to move once more in the same turn. The number of units affected depends on the game; in the earlier games, all adjacent units are affected (allowing a maximum of 4 units to move again), while from Fire Emblem: Thracia 776 onwards, it affects only one unit chosen by the player.
In TearRing Saga: Utna Heroes Saga, Dance appears as an exclusive skill that only Plum is able to learn. After dancing 150 times, Plum gains the additional ability to either increase her target's Strength or Magic by 10, or halve the damage target takes for the rest of the map, although this effect is triggered at random.
Sing also appears as a skill exclusive to Lyria. When used, Sing heals all party members around Lyria and also has a chance to refresh them. The amount of HP restored, chance to grant another turn and range all increase with usage, maxing at 5 HP, 20% chance, and 4 tiles respectively.
Fire Emblem: The Blazing Blade feature Rings that can be used by dancers and bards to perform alternative dances/songs. These dances/songs will not allow a unit move again; instead, they will give them certain statistical boosts for one turn, such as increased Defense or a boost to their Critical rate. Like most items, these rings have limited Uses.
In Fire Emblem Fates, the singing ability is exclusive to Azura as long as she is in the Songstress class. If Azura has the Inspiring Song skill equipped, her Song will not only revitalize ally units, but also boost an ally's Skill, Speed, and Luck by 3 points for the turn that she sung for them.
In Fire Emblem Heroes, the Dance ability is currently available to Olivia and Ninian while the Sing ability is exclusive to Azura. Unlike most skills, Dance and Sing cannot be inherited. If a unit has Dance or Sing, they cannot use this ability on any unit who also has those skills equipped.
