As we all know, note block plays variant musical instruments, which only depends on the block below itself. But it sometimes makes us disappointed that vanilla provides only 16 kinds of musical instruments, so that we find it hard to perform a song with many instruments well.
Why don't you try this out? Instrument++ mod adds more musical instruments for note blocks, and especially, some of them are the traditional chinese musical instruments!
The following shows the added instruments, pitch notation and blocks to be placed under the note block:
If you also install JEI, pressing U is a way to show you each block stands for which musical instrument of note blocks.
Have fun and enjoy your music world!
