Xena: Warrior Princess
The theme music, composed by Joseph LoDuca, who also co-wrote the lyrics for the songs in "The Bitter Suite", was developed from the traditional Bulgarian folk song "Kaval Sviri", and was sung by Le Mystere des Voix Bulgares. In the Hercules: The Legendary Journeys episode, "Unchained Heart", in which Xena is introduced, the original "Kaval Sviri" is the music used to announce Xena racing into battle.
