Automatic Note Block Organ Plays The Star Spangled Banner with Firework Show (No Mods or Commands)

This is made in vanilla creative mode with no mods or commands.
Stone walls can be used as tileable vertical instant wire and activated by observers and trapdoors. I use this mechanic to encode the music, one note at a time. This is similar to how a real player piano would work with a punch sheet, or you could think of it like a music box. The organ version is more complicated than the piano version as notes need to be told when to turn on and then when to turn off. The flag flaps automatically with the music and the fireworks are synced with certain parts of the song.
