If you're sick of hearing the same ol' harp solo for the millionth time, this mod allows you to adjust the volume levels of instruments. Simple as that! Not much else to say, just a 1-hour-made mini-mod.
Compatibility
Probably requires Royalty or Ideology DLC as I'm not sure instruments exist outside the DLCs.
This is a skin-deep mod that makes no changes to save data, and can be added or removed at any time.
