Note Block

A note block is a block that emits sounds when, or powered with redstone. The sound produced can be altered in various ways by using it or putting certain blocks directly above or below it. A note block's sound played repeatedly can be used to direct allays to stay nearby and drop collected items near it.

Natural generation
Note blocks generate in ancient cities.

Breaking
Note blocks are most quickly broken with an axe.

Instruments
The instrument played depends on the material of the block underneath the note block. Note that these are groups of blocks defined by the code, not just the individual block.

Powering note blocks


Note blocks can be powered in a variety of different ways following normal redstone principles; however, some ways of powering note blocks are more convenient than others or produce unexpected results.


 * When a note block is powered by a button on its side, it does play a note, but is often difficult to hear because the sound of the button can overlap the note block.
 * Because note blocks need space above them, note blocks powered by pressure plates or redstone directly above them do not make a sound.

Interaction with allays
If an allay hears a note block play within 16 blocks of its location, it tries to path find to the note block and then spends 30 seconds around that particular note block, seeking items around it and returning them to it instead of its player. After 30 seconds, the allay returns to targeting its player. A vibration particle emanates from the note block and reaches the allay to indicate the allay has locked on to the note block. Because the allay and the note block interact via a vibration particle, placing wool between the note block and the allay can prevent this interaction.

Fuel
Note blocks can be used as a fuel in furnaces, smelting 1.5 items per block.

Block data
$$, a note block has a block entity associated with it that holds additional data about the block.

See Bedrock Edition level format/Block entity format.

Trivia

 * Because a note block is a wooden type block, a note block directly on top of another one produces a string bass sound when powered.
 * $$, note blocks have the second highest number of possible block state combinations, at 800 or 1150, beating fire's 512 and behind redstone dust's 1296.
 * In Creative mode, the only way to hit a note block to play it without breaking it or changing its pitch is by doing so while holding a sword.
