Today I have something innovative to show you: Note Block Displays!
This resourcepack adds an "Display" to every Note Block. On that Display you can see which instrument and which note the Note Block is using. This is the first resourcepack that allows you to see that. And you do not even need to install any mod to use this resourcepack. The feature to create a Block Model for every note was added in the Minecraft 1.13 snapshots. So this resourcepack is only available for Minecraft 1.13.
For more information on Note Blocks, you can visit the Minecraft Wiki thread:
Note: Please, wait 5 seconds after clicking on the download button and a yellow "skip" button will appear in the top right hand corner. Click on it to direct-download the resourcepack.
