Ellie Wackerman of Agudas Achim Congregation in Alexandria, Virginia, has taken the time to mount a Torah Trope tutor on the web. She provides standard Torah trope for Shabbat and holidays, including High Holy Days, the three pilgrimage Festivals (Shalosh Regalim) of Passover, Sukkot and Shavuot, and the trope for Purim. Ellie has a provided simple clear notation along with the trope.
