As above, the game is Golden Sun The Lost Age. The song is specifically the overworld song AFTER the jupiter lighthouse is lit and the two parties reunite.

Instrument-Considering i know enough of composition (and can find the Display in concert pitch button) any solo instrument can work out for me. I would hope that it can be written with just one or two parts though. I would love to do this myself, and submit it to here, but I really don't have the ear needed. As in, I suck :)

thank you in advance for even looking at this topic
