Original: Franz Schubert's Ellens dritter Gesang (D839, Op 52 no 6, 1825) is often performed with the Ave Maria prayer sung in place of the original text; this is misidentified as "Schubert's Ave Maria".
Simplified: Franz Schubert's Ellens dritter Gesang (D839, Op 52 no 6, 1825) is often misidentified as "Schubert's Ave Maria" because it opens with the greeting "Ave Maria" ("Hail Mary"), even though it is not a setting of the traditional Ave Maria prayer.
