The note block is a musical block from Minecraft, the sandbox game developed by Mojang, that plays a single note when activated by redstone power or by a player. Builders quickly began using rows of tuned blocks to recreate songs inside their worlds, and clips of those creations spread through gameplay videos and streaming. Because the chime is so closely tied to Minecraft building and redstone experiments, creators still use it today as a shorthand for the game itself, for creativity, and for a light, nostalgic video game feel.
