Okay. So I'm thinking that the music can do special things. Like kinda of a magic thing. Maybe like if you have lvl 50 music, you can conjure a pick or axe by playing the instrument. But, the ax/pic will only last like 100 ores/100logs. Maybe be able to play a song at lvl 99 that heals you, but has a cooldown. And to train it, you could play in certain areas that has a crowd of NPCs and you would gain exp and a little money. I think it would make an interesting skill, considering all the different possibilities. You could sing, guitar, woods, brass, percussion, strings. Man, this is pretty awsome.
