I had an interesting idea for Generation VI, or possibly Grey or Ruby/Sapphire remakes, inspired by by the slight differences in Reshiram and Zekrom's battle themes. The idea is basically that in the next pokémon game, there should be a slight difference in the instruments used in the Gym Leader battle music, based on the type that Gym Leader uses. A Normal Gym Leader would just get the basic Gym Leader battle music for that generation, and each of the other sixteen types would get a single instrument added to it. Just to give some examples of what might be used for each type:
Rock: Extra percussion, I guess
Water: Maybe a harp or a flute?
Electric: Electric guitar
Grass: A think some kind of flute would fit best
Poison: Maybe an acoustic guitar
Psychic: Organ or accordion
Fire: Trumpet
Ground: Not sure. Maybe just have the music echo a bit so it sounds like your in a cave
Flying: Not sure
Bug: Not sure, maybe some sort of flute
Dark: Contrabass
Ghost: I think an Organ would fit best
Fighting: Percussion
Steel: Again, some kind of percussion, probably a metallic sounding instrument
Ice: Piano or violin
Dragon: Hmm... Tricky. Maybe all of the above together?
What do you think of this idea?
