Rosen
by Violunae
Rosen, a lightweight mod, expands the noteblock system with 18 added instruments such as saxophone, organ, sitar and box timpani.
What it does
Rosen adds 18 noteblock instruments, among them saxophone, organ, sitar and music box, with sound design kept at the level of vanilla Minecraft. A quality-of-life addition lets a noteblock play any existing instrument while standing on a block of a similar type, so the instrument choice is not fixed by the block below.
Custom instruments can be added in 1.21.1 and later through a datapack. A new JSON file named after the instrument, placed under the data.rosen namespace, defines the noteblock instrument. A second file, a block tag for noteblocks, lists the blocks that trigger it, and the used instrument follows the regular tag format. Players and server owners on Fabric, Forge or NeoForge get the same content, since the environment is client and server and the mod is published for 1.20.1 – 1.21.1 across seven release versions.

Better Note Blocks is a Forge-only, client and server mod for 1.20.1, open source under the MIT License. NoteLock is a Fabric server-side only mod for 1.20.2, licensed under the MIT License and not open source, so players can join without installing it.
