There are times when I could really use a 5-line musical staff drawing tool. When teaching, I write down the different things we talked about, mostly as a record of what happened that week. I use blank paper for that. If I want to write in notation, I will draw a staff freehand, which sucks. I once had a tool that you could dip in ink, the drag across the page to produce a staff. It was a mess, with ink. Is there a ballpoint pen version of this? I looked around inside the internet and didn't see anything. Any ideas?
