Vanilla note blocks play based on specific blocks, or material checks. Many of these should already catch TFC blocks (i.e. stone, wood, etc.). We may want to add TFC variants of these blocks to the vanilla blocks, which can be done with a NoteBlockEvent listener.

Considering this investigated, as we determined that the majority of note block sounds well, they work, and they work with TFC block types (based on materials). And I don't really think adding TFC-specific note block sounds is worth it, also considering thematically it's pretty anti-realism.
