Hi @bobidle Thanks for working on the music. It's been a while since you've worked on this pull request. I see it is still in draft, are you still working on it? If it is ready, please mark it as ready for review, then we will look at it! The same holds for '💻 Add music note H as an alias of music note B #6226

Thank you @AnneliesVlaar, at the moment the code does not work for all languages, but it should add a demonstration how it could work. I still want to work on and finish it. Also i want to make the notes available as Do Re Mi Fa Sol La Ti where the naming could also be different by country.

That's very interesting @bobidle, thank you for diving into it! We're looking forward to the result and will wait for when it's ready to review.
