This is a durable, laminated Grand Staff that is dry erase, so it can be used over and over again for hundreds of lessons. It's so tough, it cannot be torn. Draw in notes and symbols or use the matching 46 pieces, note and symbols (sold separately) to teach note names and values, rhythms, composition, intervals, chords, rests, etc. It has corner grommets for hanging or you can affix it to a wall in your own way with tape or stick pins. If residue builds up, use a dry erase White Board liquid spray cleaner to refresh and completely clean the surface. Students can construct/compose their own melodies, and teachers can draw lessons of all types. The Dry Erase Music Staff is 5 feet long.
