Omg, I have no idea how to edit my post. I tried to post this as a PDF, but the file format isn’t supported so I converted it into a jpg. Open in a new tab and really zoom in to see.
I made this in MuseScore using Arcandius’ code.
There is usually a little pencil icon next the the “reply” link, but for some reason a lot of the action buttons (emoji, likes, etc) have not been displaying on the forum. If you mouse over “reply” and move the cursor left, you should see the “edit” pencil.
