Starting from Minecraft 1.19.30, music is already built into the game, the guide for this and newer versions is not relevant.
First, you need to open the Marketplace from the main menu.
Now go to the search and enter the query Music.
Find a music set by flipping through it a little. It will be marked as Free.
Click on it, but note that if you are not logged in to the game, you will see a window asking you to log in to your Xbox Live account.
After completing these steps, click Download, the size of the set is 195 MB.
Wait for the download and the import to finish.
After importing, the game may hang up and throw it back to the market, but don't worry. Just restart the game and the music will already be on!
There are no sounds on the iOS device?
You might have Silent mode enabled, just turn it off.
If you can't download the set from the game store, then it is also available on our website — The original set of music for Minecraft.
