When you're searching for a printable piano diagram with notes and other indications, you mostly find something that's not suitable for the size of your piano.

Therefore, I created a scalable graphic, so you can adjust the size of all keys for any kind of keyboard, add/delete stuff and edit everything as you wish.

The file can be downloaded for your own needs right here:

Final result:

Link to the SVG file:

This looks really useful. I have an upright grand piano here.

You should upload the svg directly to the forum if you can, it'll keep it as a backup to your website.

@bulevardi Nice. I used to play, but sight-reading was tricky for me. This would no doubt help schools and music teachers.
