The Copper Horn is crafted just like how its original variant was: a goat horn and 3 copper ingots in a "v" shape. Like how it was in the old betas before it was removed, each goat horn type yields a different copper horn to play a unique sound! See them below:

*Ponder Goat Horn = Fearless River Gift Copper Horn 

*Sing Goat Horn = Fresh Nest Thought Copper Horn 

*Seek Goat Horn = Great Sky Falling Copper Horn 

*Feel Goat Horn = Mumble Fire Memory Copper Horn 

*Admire Goat Horn = Old Hymn Resting Copper Horn 

*Call Goat Horn = Pure Water Desire Copper Horn 

*Yearn Goat Horn = Secret Lake Tear Copper Horn 

*Resist/Dream Goat Horn (name of this one will depend on whether you are playing on 1.19.2 or the current beta) = Sweet Moon Love Copper Horn 

Similar to the Goat Horn, the Copper Horn doesn't have any real gameplay function, just being a fun novelty item, but it does have a bonus use of being able to have it's sounds be detected by Sculk Sensors and Wardens. Try to collect all of them if you can! NOTE: Unlike the old Copper Horn, this one won't play a different sound if you crouch or look up, I don't know how to add that sorry.

Music Discs have also been revamped in this add-on, at least through how you obtain them. No longer will any discs drop when a skeleton shoots a creeper, instead you must now find fragments for discs hidden in chests around the world and create a disc using a specific item alongside them! Can you collect all the discs through this way?
