Command Block Playable Piano in Minecraft

This design lets you actually use your number keys to play the different notes, allowing for some incredible music (wow). Listen I'm just gonna throw this here and see if anything happens: tutorial. If you searched for "minecraft piano tutorial" or something, then no, this isn't a tutorial, but I'm just curious to see if it increases views. If it does, don't worry, I'll actually include a tutorial type thing in future videos rather than just throwing the word in. Music Used: Outro: Pachelbel Canon in D
