As I began teaching myself violin, I was surprised at the total lack of free flash cards for musical notes. I created these in Photoshop and pasted them into a MS Word template for Avery 3612 and Avery 5371 Business Cards.

Print Page 1 on a sheet of cards, flip the sheet over and print Page 2. Repeat for Page 3 and 4 and you'll have a set of Treble Clef flash cards to drill yourself with!

The Zip file on the Downloads page contains both MS Word and Adobe PDF versions.
