As you probably know and appreciate, accidentals are a huge part of written music! If you are a musician, you probably spend most of your time reading music rather than writing it, so this type of article might be of limited use to you (unless you are just curious about the topic). However, if you are someone who enjoys writing or composing your own music, I hope you learned a lot here! Keep in mind that these days a lot of different software is available for music writing, which takes care of the placement of accidentals for you according to the rules outline here. Good luck!
