Ethan’s Theme – Pokémon HeartGold/SoulSilver

This is “Ethan’s Theme” from the Nintendo game “Pokémon HeartGold/SoulSilver”.
It is composed by Shota Kageyama.
The chord progression and other details of the song are mentioned in “Lyra’s Theme“.

Here I’ll write about the differences.
Key: this is B major, while “Lyra’s Theme” is Eb major.
Rhythm: The accompaniment on the back of the third beat is one tempo slower here. (In other words, “Lyra’s Theme” is anticipated.)
*There may be others, but the ones I figured out are above.
