Ideal for a town in an RPG. Safe, accoustic vibe.
I should definitely use this for something. Maybe a menu, a short section or a single level... something with little or no risk of death/failure.
I can definitely hear a sort 'RPG generic small town' vibe to the melody. Vaguely similar to Snes RPGs, it reminds me of a dozen and none.
I like how you used real instruments, but kept an old-school simple melody. I love the soft drums and also the way you share the melody between guitar/piano. the soft violin only became noticeable after a while. That sorta ties it together well as do the bursts of guitar during the piano playing.
What's the instrument you start with? Was the guitar real and the other instruments fake? (That's my guess...)
You've definitely added onto the melody enough to make it interesting to listen to for a while.
It's on repeat just now and I find myself getting tired after... I dunno... 7 minutes. Yeah. It's lost most of its charm now.
I think the piano should maybe be a touch softer and played slightly more legato. Also, maybe just as you have bursts of guitar during the piano part, maybe you could throw in a few piano chords...
Loops well.
So final thought - too short for a full game (as I'd expect for a loop of this length) but great for an upbeat acoustic-style menu, a single level of a puzzle game, an upbeat platform level with little (or no) risk of death or maybe even a town in an RPG. Heh.
Great stuff.
