Fanfare of the Heart was the first ending theme for Pocket Monsters Best Wishes. It had two variants but the animation was the same in both, only the lyrics changed to showcase a different verse.
The song features Satoshi's Pokémon playing instruments as they march to the music. Pikachu plays the drums, Mijumaru plays the Tuba, Tsutarja plays the flute and Pokabu plays the bagpipes.
Throughout the ending, various pictures of the main characters are shown which showcase aspects of their daily activities such as running through a field, camping by a fire and posing during battle.
