Software that makes piano keyboard diagrams?

[berlinpose2]

New to this forum, but looking for something specific.

When I'm make worksheets for my students or arranging a piece for them, I often need to insert a diagram of a piano to illustrate what I'm saying. I usually either use a quick editing program (like MS Paint) + an image I find on Google research or just write it by hand and take a picture of it. But it'd be nice to have something on the computer that can do it for me.

What I mean is, to be able to open a program and choose which keys and how many there are (like from C-G with the black Keys where they need to be) and maybe be able to put symbols/dots or words/letters on some of them, the way you do for early beginners who are learning about hand positions for the first time.

I've tried googling it but I just can't think of what words to search to get this specific product. Has anybody ever heard of something like this? Because if it doesn't exist, it really should haha.

I tried to find something like that myself a couple of years ago and never found anything. In the end I had to build a makeshift one myself. It's not great but it serves its purpose. I may put it online one day when I've ironed out the bugs and build a proper interface.
