Could you share your rules of capital letter usage?
it's not perfectly defined, but some of the general principles are: chord symbols are always capitalized (except for "b" when it's used to mean "flat"). Acronyms are almost always capitalized. the letter L is often capitalized whenever it would otherwise be in danger of being confused for I or 1. the letter "i" when referrring to self is never capitalized. the start of sentences may occasionally need to be capitalized if i feel there is a tone change, or if there should be a decisive break in between sentences, OR if there seems to be a lot of other punctuation in the area and it would otherwise be unclear that it's the start of a new sentence. It's used for emphasis, the same way bold would be used, and the reason i prefer capitals instead of bold is because it's much more likely that the capitals will actually show up on any device, where as bold might get lost somehow. And also if i'm just simply referring to the letter itself, such as the letter F, it is most often capitalized, because that is probably the way that most people think of individual letters. The exception to that, of course, would be the letter "i", which, again, for similar reasons to why L sometimes gets capitalized more often, "i" should be capitalized less often because, similarly, it runs the risk of being confused with l or 1. I also often use capitalization for signage, especially with short contents, such as "STOP" or "EXIT", especially when i am trying to replicate signage that people are familiar with in the outside world
