dragon cance on dragonite

Please help. Since im playing emerald, dragonite doesent learn dragon dance by leveling up so i think i have to breed.
What pokemon do i have to breed with dragonite so i could get a dratini with dragon dance?And male or female?
also if i make dragonite hold everstone, will it get its nature?

Breed a female dragonite with a male salamence. Salamence can learn dragon dance

on emerald?

Male Gyarados+Female Dragonite (dont stop this step until you get a MALE dragonite with dragon dance.)

Male Dragonite W/Dragon dance+ (insert nature) Ditto

And wait until you get the nature you need and you shold have it

does gyarados have to have dragon dance when i breed with dragonite?
