Standard Size Staff Notes and Key Signatures contains 80 cards featuring all the natural notes on the staff and ledger lines, notes with accidentals, and key signatures. Each note card has the answer pictured on a keyboard on the reverse side. In addition to the notes with accidentals, the Standard Size Staff Notes and Key Signatures differs from the Music Flashcards in that it has smaller notes and staves, closer to the staff size of “standard” engraved music.
