These are flash cards that Mary Kay made for her students and offered to share.  They include time signatures, dynamic levels, basic staff items, all harp symbols used in the Suzuki Books 1 and 2, and all other musical symbols used in Books 1 and 2.  Print them on colored cardstock (I always use yellow for this set) and cut them apart.  If you want them to last forever, cover them with clear contact paper and trim the edges.  Also included is an explanation of all the symbols.   Click this link for a PDF file:  Flash Cards    Hope you enjoy them!
