Creating note block music is an extremely fun way to spend time in Minecraft. Note blocks are extremely versatile, and players can create an entire song with a simple redstone configuration.

Note blocks let players play a certain note belonging to different instruments. With these nifty blocks, players can even make full length instrumental music in Minecraft.

Using the note block repeatedly will then make the Allay swiftly swap the cake it's holding for the cake on top of the note block, making the 'Birthday Song' trophy / achievement unlock.
