Sounds From Afar

Exploration Stage: City Hall
From: Cardsharp
Description: We've found four instruments. Only one more left, but which one? What's that sound? I bet my top hat, it's a harmonica! This is the last instrument. Hurry, bring it here.
Completed: You won't believe it but this harmonica is mine. Well, not completely mine. I won it and then gambled it away again to the conductor. I bet the drunkard lost it.
