Epona's Song

This spell lets you convince all nearby beasts that you mean it no harm. It must see and hear you. If the beast's Intelligence is 4 or higher, the spell fails. Otherwise, the beast must succeed on a Wisdom saving throw or be charmed by you for the spell's duration. If you or one of your companions harms the target, the spell ends.

Or, you may use this spell to summon any mount you have that is not mechanical, as this song travels across the wind and summons your steed.
