Note Block

A Note Block is a block that plays a single note when struck by the player or powered by redstone.

Obtaining
Note blocks are most quickly broken with an axe.

Usage


Note blocks play a colored musical note when or when powered by redstone. Redstone current only causes the note to play once, even if it is a continuous current. A note block must have at least one block of air above it to play a sound. Notes can be heard up to 48 blocks away.

Note blocks will play when next to a powered block. Each time a note block plays a note, a note particle will fly out of the top, with the color depending on the pitch (but not the instrument).

on the block increases the note pitch up a half step, with a total of two full octaves being available to play for each instrument (bass is two octaves lower than the standard range, giving you four octaves of effective range if you combine instruments). The range of notes span from F♯3 to F♯5. After reaching the highest note, pressing use again resets it back to F♯3, as does breaking the block and picking it back up. The exact pitch to pressing assignment is shown below.

Alternatively, there is a graphical version available:



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



Instruments
The instrument played depends on the block underneath the note 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 switch on its side it does play but is often very difficult to hear since the sound of the switch activating is so loud.
 * Since note blocks need a space above them, note blocks powered by pressure plates or redstone directly above them do not make a sound.

Sequencing
It is possible to link together a set of inverters, connected to note blocks, which are then played after each other when the first inverter is given power. This can be used to create songs, without having to manually give power to every note (through pressure plates for example). See also: Redstone circuits.

Redstone repeaters greatly simplify the process of timing note blocks in sequence to make melodies. The delay can be set to one, two, three, or four redstone ticks, which is equivalent to 0.1, 0.2, 0.3 and 0.4 seconds.

Another way is by sending a minecart down a railway with detector rails and powered rails and connecting the detector rails to note blocks beside the track. This is useful if you want to hear your music without the degrade in sound as the note blocks play from farther and farther away. However, it is recommended to turn the Players bar in the Sounds menu to 0% to cancel out the minecart sounds, or use a customized resource pack.

Chords


When creating melodies in Minecraft, one will often want to play chords. This is done by playing two or more note blocks at the same time and is relatively easy. Note blocks can be tuned to create harmony or dissonance using the same semitone intervals as on piano or almost any other instrument.

Assuming there is already a sequence of note blocks powered by repeaters:
 * Additional note blocks can be placed adjacent to it. when the main note block is powered the adjacent note blocks also become powered on the same tick, creating a chord.
 * A redstone wire can be led out of the block in the main sequence. Note blocks placed adjacent to a block with a powered redstone wire on will be powered on the same tick.

Pressure plates - removing the click
Stepping on a pressure plate is a simple way to trigger a note block, but also triggers the pressure plate sound effect. The pressing/clicking sound can easily be removed by turning off the sound of blocks in the options.



Trivia

 * Note blocks start at the pitch F♯/G♭, which is unusual since the note has no significance in any known musical instrument.
 * The sound files for the note blocks can be found in assets\sounds\note, you can see that the piano sound is named "harp" and also that there is an unused sound called "pling".
 * You can tune a note block even if there is a block above it, however the note will not be seen nor will any sound be made.
 * Note blocks use the same texture as jukeboxes but the top texture is the same as the side textures. (In some resource packs, however, you will see that there are two different image files for the noteblocks and jukeboxes, named "noteblock.png" and "jukebox_side.png" respectively.)
 * Triggering (playing) a note block or changing the note played does not count as a block update, however, it provides a comparator update and so this can be detected with a CUD.
 * Note blocks are block entities and like all block entities cannot be pushed by pistons. It needs to be a block entity to store what note it's currently set to.
 * Note blocks can't play wind instruments.
