Here is a mod I kinda branched off of the Lord of the Test harps and things.
Contains: Large and Small Steel and Golden bells, Trumpet, Fanfare, Gong, Harp, and Horn.
the Large bells are placed and then punched to make their sound, all others you just left-click while equipped.
Credits to Amaz and Thomas-S for their part in this mod. Let me know if I missed anyone.
I guess the license is LGPL, since that's what the LOTT part of the mod is.
