There are large, smaller and miniature flashcards on the ‘Help with Music Theory’ site. These are the larger flashcards. Each flashcard is 14.5cm x 10cm when cut out. It includes all the notes from C2 to C6, which is 4 octaves of the most used notes on the piano. They download as a PDF prints out onto A4 card or paper (card is recommended).
