Grand staff cards are used to teach students about the staff, the clefs, the names of the lines and spaces, and much more.
These cards help students:
Learn about the staff and clefs names
Learn the difference between a line and a space
Learn the names of the notes on the grand staff
Practice intervals
Learn the relationship of the notes in the different clefs to their instruments
Practice triads and inversions
 
Notes
The grand staff is slightly modified so the space between the two clefs is only enough for the three notes found between the clefs: B, middle C, and D. This makes it easier for students to learn the relationship between the two staves.
Bass, alto and treble clefs together on one staff
Open strings on the violin, viola, cello and bass
Treble clef with notes originating from G
Bass clef with notes originating from F
Alto clef with notes originating from C
