I arise from the grave because I have a neat idea for a remix of this song that, so far as I've seen, hasn't been done yet. Since I don't have the talent to do it myself, I figured I'd share the idea in the hopes that someone more proficient than me might do it.
So if you've played the new Pokemon games yet, you know that each island has its own guardian deity Pokemon called a Tapu. They have their own battle theme which is literally, at least in my opinion, the best legendary beast battle theme the series has had.
Here's the original
Now for the idea:
There are four of these Tapus: Tapu Koko, Tapu Bulu, Tapu Fini and Tapu Lele. While similar to each other in certain aspects of their appearance, each one is unique even though together they form a cohesive whole (because they're known as the Guardians of Alola). Because of that, I think it would be kind of awesome if there was a remix made of this song made with only 4 primary instruments--one for each Tapu that encompasses that Tapu.
So for example, this is what I was thinking (though if someone decides to run with this idea they can obviously pick whatever instruments they think fit better):
According to its dex entries, it's known for its sense of curiosity, its ability to confuse opponents due to its fast movement speed, and its quick tempered nature even though it instantly forgets whatever made it angry. Of the quartet, it's the Electric type one. Given these qualities, the best instrument in this hypothetical remix that would represent Koko would be an electric guitar, most likely holding the melody.
Lele is the Psychic type of the quartet. Her dex entries aren't too enlightening. In one she's said to be guilelessly cruel while in another it's said her scales restore good health when touched. She's based on a butterfly, so this nature and life-giving property to her gives off a sense of naivety. Perhaps a little airy, since her scales are said to scatter as she flutters about. So for her, an instrument with a similar airy nature would probably fit. My candidate would be wind chimes, but I'm sure there's many other instruments that would give off the same effect. She'd be like the ambiance of the remix, fluttering in and out of the song as she pleases.
His nature is lazy, according to his dex entries. Yet, amongst the quartet, he's also the most physically strong, both in terms of stats as well as implied in his dex entries with how he can uproot whole trees and swing them around easily. A strong Pokemon who prefers to not have to work much when battling. The obvious choice of instrument for him would be drums and he'd most likely hold the bass in contrast to Koko who'd have the melody. Probably a similar drum to what's in the original song, I imagine. One you'd strike with powerful impacts that would only occur every few beats. Type-wise, he's Grass.
And finally, we have the mysterious Water type in the quartet. Unlike the other three who take active roles in anything, Fini is a much more passive pokemon. Although she wields great control over water, according to her dex entries she creates fog so dense that her enemies become confused and destroy THEMSELVES without her ever lifting a finger. This is reflected in her stats as well, as both of her defense stats are the highest while her attack stats are average at best. I don't know any specific instrument that would properly reflect her, but given her passive nature and her associations with water, whatever instrument would be hers in the remix would need to be one that flows like the water she controls, but is similarly passive throughout the remix.
These individual elements combined would then be what makes up the entirety of the remix.
What do you think? Does this sound interesting and challenging to you? I'd love to see many people try this out!
