Add New Instrument When Using a Noteblock That's Placed On a Specific Block

After they added trumpet Instrument into Minecraft Noteblock on the new update, i think it's better if Mojang added more Instrument to it. Like if Player place noteblock on amethyst it will make a sound like glockenspiel. I guess make a gamedrop of this will be great. I recommended to name this gamedrop with "The Musical Era". Also add a new music disc because this will match with the name
