This is a Grand Staff with keyboard letters for 4 octaves. This free resource is great for students learning the treble and bass pitches. I put two of these on one page and then have a smaller paper for students to use. If folded right it can have only treble pitches shown and only bass pitches shown. Then on the back you can draw each staff with the letters of lines and spaces.
Enjoy another great educational handout from JC Music Resources.
