These tracks are based on an RPG concept about colors. They all use Famitracker and the VRC7 expansion.
Legendary Glow was a sort of main theme or opening scene. The main flute melody was meant to be used as a recurring motif.
Original module comments:
"#3 Legendary Glow
The classic "opening theme," for a title screen or maybe an
opening cinematic. I'd hoped to introduce a melodic theme with
this song that could be reused in different contexts throughout
the project (Shining Force and Langrisser II had opening themes
like that) but the main melody on the flute is probably a
little too complex for that."
