These can by used by beginners learning piano to help learn the names of the notes and to compose short songs. The notes are not marked because they can be used on the treble or bass staff. You can write the various notes on the back with a marker to use them as flash cards.

They interlock and can be rotated to lock upside down, so you can print two sets of these to cover all notes in the staff range.

The gcode version includes a filament change so the background and lines/notes can have contrasting colors as seen in the photographs.
