Playing Lightsong as an Exemplar (PF2e)

[elsecaller27]

Hi everyone! 

This is my second post (after the intro post), so I hope I'm in the right place. 

My GM for Pathfinder suggested I might play an Exemplar in our next campaign. tl;dr it's a class where the character has some divine powers (but different from a cleric or paladin). At first I thought that maybe I could play a Hercules or Maui type character, but I always try to put a different spin on my characters. It hit me this morning that Lightsong might be a good fit. 

How would you play Lightsong as an Exemplar?
