music by player

[WellFooled]

Specifically in this game, nothing, but typically in FF games the only people that have ever played music have been bards. It's not that no one else -could-, just that up to this point no one else -has-. (Note, I am not counting Celes' singing in VI as playing music.)

:P So what you're saying is that there's nothing in lore that would be against this idea?

This may seem very nitpicky, but the playable character in four main series Final Fantasy games plays the piano, the lute is played in two, the bell is played in one, and Geomancers, Ninjas, White Mages, and Cait Sith all use instruments in the main series without being bards. That isn't mentioning the amount singing playable characters or npc who also have musical forays or Final Fantasy spinoffs. If you're worried about precedence, I wouldn't sweat it.

I would love to see this included in the game, side content like this I think is some of the best world building.

Edit: I also forgot the concert in FFVIII at Fisherman's Horizon! Where the player characters play the violin, flute, Acoustic Guitar, tap, Piano, Sax, Electric Guitar, and Bass!
