Query: Very helpful learning tool

I purchased this bulletin board set for my beginner piano students who need extra help with learning the notes. the charts are clear, colorful, and durable. Also they attach easily to a door or painted wall with tacky gum so they can be repositioned as often as necessary. My students use the notation charts all the time. As for the musical symbols...not so much but are still nice to have on display. The wipe off staff charts are great. You can cut them to size if you want for smaller practice boards. I have even had adult students comment on these charts. Definitely worth the buy
