New Noteblock Sounds

We haven't gotten any new note block sounds (as far as i know of) for quite some time now, so i think that is time we could get some new ones! 

Some examples might be:

Pipe organ (or steam whistle etc.) for copper blocks (or similar)

A heavy "rain bow-esc" sound for something like netherite blocks

An Airy sound for something like sponge blocks or tinted glass 

etc.

And again these are just ideas, and can be improved and iterated on later
