The idea is loose because Red51 may end up thinking of a better idea on how to tackle this. He may ignore my idea all together with how 'ambitious' everything is on every front.
I was thinking you could grab a piece of paper, grab a pen to then select boxes (similar to Excel/spreadsheet) to then add in notes to then have it play out in that keyboard manner. The way you activate notes on the keyboard would be the notes you use on the sheet music. Any space would be a silent note that won't be played, yet it would play in a normal speed. If Red51 wants to go further he could set a temp speed on the sheet music we could go by to slow the music down, and maybe have sections where tempos can be changed on the fly. It's all up to what's possible, and what can be made possible.
An alternative way would be to use actual musical scale, something Red51 would have to dig deeper, for deeper musical control by using actual musical notes to translate back into the instrument to hit those specific notes. Not the keyboard pressed notes, but the actual notes you find in a musical sheet music that goes deeper so talented musical people could share their talent to others. The f sharps, and triple notes, among others. The more complex related stuff could be an addition so people with musical keyboards could go fancy, recording that into sheet music notes, not the excel/spreadsheet box idea above.
Both ways could then be saved as special sheet music blueprints that we could then up onto Steam workshops (or save into a specific folder) where it behaves similar to a blueprint & poster manner to be transferable from one world to the next. It would be saved into a folder for the game to then register it, and so it's saved from constant world hops.

- Bonus:
We would place a sheet music stand anywhere (ideally in a cafe/pub/relaxing area) where it's empty. We would have to place sheet music on it, similar to the crusher with stone, so it would then trigger our character to play music when we interact with that music stand. We would play music from the sheet music placed automatically, and similar with NPCs so they can play. To have them play in a group we would have to somehow notify the game we want a group playing on cue, maybe that conductors stick & podium in the vacinity.
Yeah, there's many ways you could also do it, just that this way seems to fit the 'Risin World way', type thing.
