Here's a little quiz to help you study the treble clef. You can either answer by pressing the key on your (typing) keyboard that corresponds, or by using the mouse and clicking on the piano image below. If you use your mouse, you will see hints as you move your mouse over the piano image.
Before you can use your computer keyboard to answer, you must first click on the flash movie to activate it.
If you want to focus on sight reading just the lines above and below the staff, check out this tutorial.
