This latest product from the Piano Studio of Amber Staffa is an activity book featuring 6 popular Christmas Songs that are all missing random notes throughout the pieces. As students follow along with the words, they must use their ear to figure out where the missing notes should be drawn on the staff.
It's great practice for working on aural recognition of high/low and intervals. They're ideal for private lesson teachers or general music teachers who have tonal instruments like xylophones available to them in their classroom.
The first 5 pieces are in the key of C and the last in is in the key of G.
