Flutes

The flute item would be found in several structures the could have one been inhabited by people such as jungle temples, desert temples, ancient cities or in the loot tables for trail ruins and drowned cities. Flutes would function similar to goat horns in the fact that each one would have its own short song played when holding right click. Different songs can be special to different regions or structures. Flutes could also be played by a villager as a small random encounter similar to piglins dancing after a successful hunt. The villagers arms are already in a similar pose for playing a flute and could lift up slightly similar to when you hold an emerald in front of them. A villager playing a flute could have the village children migrate to it for the duration of the song. This would give villages a sense of liveliness and community that they seem to lack at the moment and make it feel more immersive as you explore your world. This also gives a chance for music to be experienced in Minecraft without grinding for music discs or spending diamonds on jukeboxes.
