{{featured|March|2020}}
'''Sound Blocks''' are one of the ten [[categories]] of [[Blocks|Scratch blocks]]. They are color-coded pink/magenta, and are used to control [[sound]] (and formerly MIDI) functions.

There are currently 9 Sound blocks: 8 [[Stack Block|Stack blocks]] and 1 [[Reporter Block|Reporter block]].

== Music Extension ==
{{main|Music Extension}}
Instrument blocks (such as drum, note, rest, and tempo) were originally Sound Blocks in older versions of Scratch, but in [[Scratch 3.0]], they were put under the Music Extension instead. This decision was made in order to prevent confusing New Scratchers.<ref>https://github.com/LLK/scratch-vm/pull/769</ref>

==Blocks==
{{note|Click on a block to learn more about it.}}
[[Scratch 3.0]] has the following 8 Sound Stack [[blocks]]:

* [[Start Sound () (block)|<sb>start sound [pop v]</sb>]]
* [[Play Sound () Until Done (block)|<sb>play sound [pop v] until done</sb>]]
* [[Stop All Sounds (block)|<sb>stop all sounds</sb>]]
* [[Change () Effect by () (Sound block)|<sb>change [ v] effect by ()::sound</sb>]]
* [[Set () Effect to () (Sound block)|<sb>set [ v] effect to ()::sound</sb>]]
* [[Clear Sound Effects (block)|<sb>clear sound effects</sb>]]
* [[Change Volume by () (block)|<sb>change volume by (-10)</sb>]]
* [[Set Volume to () % (block)|<sb>set volume to (100) %</sb>]]

Scratch 3.0 has the following Sound Reporter block:
* [[Volume (block)|<sb>(volume)</sb>]]

== Scratch 2.0 Sounds ==
{{obsolete feature|cat=no}}
Scratch 2.0 MIDI instruments had a fairly low sound quality because of Flash's small sound library. Later, the [[Scratch Team]] put their own sounds into the blocks instead. This remained in place in [[Scratch 3.0]], due to it being developed in HTML5.
