Epona will answer it, or she never met you as a kid so you never learned the song.
Just play eponas son that you can get from malo as a child
To get epona you go to the lon lon ranch as a child and keep talking to malon whos in the middle of the field. After a while pull out your ocarina and she'll teach you eponas song. As an adult go back there and speak to the man by the fence. Pay the charge and ride a horse. While riding get off the horse and play eponas song. Epona will come running to you. Get on her and ride over to the bloke. Talk to him and he will ask you if you want to race with that horse say yes and pay the fee. You will then race him twice. Win both the races and he'll let you ride the horse around the ranch. Then go as fast as you while riding epona and run into the fence on the outside (the fence which would lead you into hyrule noy the other one, if you can't work out what I'm on about just run at all the fences) and epona should leap over it. And dada you have epona.
The following games you can get epona in Legends of Zelda: Ocarina of Time (Adult Link) Majora's Mask (Adult Link) Twilight Princess Four-Swords Adventure (But only once in this game)
U dont get it as an adult u get it at the ranch as a kid
I think you have to go to the ranch... Epona should be there.
the series never reveals epona's age
Epona is Link's noble horse. If you have found her you can summon her by playing epona's song with the ocarina. Or with a reed on twilight princess.
the only horse you can use is Epona
No, you can only ride Epona as adult Link.
play the game with epona play epanas song
Come back to the Lon Lon Ranch as Adult Link and pay Ingo (the guy that keeps charge of rides with Epona) about 50 or 60 rupees to race him, if you win, Ingo locks you in Epona's stable and it's pretty easy to get out because it's a short fence. (Foolish Ingo.) Jump off the fence if I had to remember and BINGO! You can ride Epona almost anywhere but if you want to ride Epona again, use Epona's Song on the Ocarina of Time. You may have got this before you beat the game where you learn it from Young Malon when you use Link as a kid.
dash when your close to the gate and Epona will jump
