A '''note block''' is a [[block]] that emits sounds when {{Control|attack|text=attacked}}, {{Control|use|text=used}} 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 [[allay]]s to stay nearby and drop collected items near it.

== Obtaining ==

=== Natural generation ===

Note blocks generate in [[ancient city|ancient cities]].

==== Notes ====

[[File:Note-Block.png|thumb|right|upright|A note block being triggered and playing a note.]]

Note blocks play a musical note when hit (pressing the {{Control|attack}} button) or powered by redstone. A note block must have [[air]] in the space directly above it to play a sound. Notes can be heard up to 48 blocks away. The volume of a note block decreases as the player gets further away from it. The volume of note blocks (as well as [[jukebox]]es) can be independently controlled by the Jukebox/Note Blocks slider in the audio [[options|settings]].

Note blocks play when on or next to a powered block. Each time a note block plays a note, a note [[particle]] may fly out of the top (if pressed too fast, notes may not appear), with the color depending on the pitch (but not the instrument).

There are 16 different instruments and 25 different pitches per instrument. Pressing the {{control|use|text=use button}} on the block increases the note pitch up a [[Wikipedia:Semitone|semitone]], with a total of two full [[Wikipedia:Octave|octaves]] and a semitone (25 semitones in total) being available for each instrument. The standard range (for harp and pling instruments) of notes span from F♯<sub>3</sub> to F♯<sub>5</sub>. After reaching the highest note, pressing use again resets the pitch back to F♯<sub>3</sub>, as does breaking the block and picking it back up.

The string bass and didgeridoo are two octaves (24 semitones) lower than the standard range, the guitar is one octave (12 semitones) lower than the standard range, the flute is one octave above the standard range, and the bells, chimes, and xylophone are 2 octaves above the standard range. This gives the player six octaves (72 semitones) of effective range to combine instruments for greater pitch coverage.

The exact pitch can be found from its {{control|use}}-count by using the following formula: <code>2 ^ ((use count - 12) / 12)</code>.

The exact pitch to {{control|use}}-count assignment is shown below,<ref>[http://www.minecraftforum.net/viewtopic.php?f=1020&t=136347 Original chart by cookingfat]</ref><ref>[http://www.minecraftforum.net/forums/mapping-and-modding/resource-packs/resource-pack-discussion/1255570 Original /playsound pitch chart by kwerti]</ref> along with the note's color, which is rendered with shading using the particle's texture.

Alternatively, there is a graphical version available:

[[File:Noteblock reference.png]]

Players can roughly check the tuning of a block by looking at the note icon.

[[File:Note colors.png]]

{{IN|java}}, the tuning can also be checked by looking at the right side of the [[debug screen]] (accessed by pressing {{key|F3}}). It is denoted as "note:" followed by a number from 0 to 24.

====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.

===== Mob heads =====
When a [[Head|mob head]] is placed on top of a note block, the sound made by the note block will instead be that of the corresponding mob's {{cd|ambient}} sound, with the exception of the creeper head, which instead causes the note block to play the {{cd|primed}} sound.

====Powering note blocks====

[[File:NoteBlockRedstone.png|thumb|A pair of note blocks wired to a [[clock circuit]] to play alternately.]]

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 [[Particles#vibration|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 [[Sculk Sensor#Vibration detection|interaction]]. 

===Fuel===

Note blocks can be used as a [[fuel]] in [[furnace]]s, smelting 1.5 items per block.

== Issues ==
{{issue list|note block|noteblock}}

==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.
* {{IN|java}}, note blocks have the second highest number of possible block state combinations, at 1150{{verify}}, 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.
