Sight Reading Challenge teaches you the 21 notes of the Bass Clef and Treble Clef. The program displays the notes on the staff, and you press the name of the letter. If you get it wrong, the program displays the name above the staff. You then press the correct name to proceed. If you manage to correctly identify all of the notes, you qualify for the Hall of Fame, and your name and time get listed for posterity. The demo version only displays 11 notes, and always in the same order. It does not support the hall of fame feature.
