Choralia provides three editions of training aids for the Requiem KV626 by W.A. Mozart, so as to best match the score edition used by the choir. Edition 1 is based on the edition published by Peters (Nr. 76), Edition 2 is based on the edition published by B�renreiter (BA 4538), and Edition 3 is based on the New Novello Choral Edition revised by Duncan Druce (NOV070529). The vocal parts of the three editions differ for the following details.

Requiem

Soprano, measure 36: in Edition 1 the syllable �na� is on the last-but-one note (C), while in Edition 2 and 3 it is on the last-but-three (B natural).

Alto, measure 12 - 13: in Edition 1 the syllables �do-na� are repeated on the last-but-one (B flat) and last (A) note of measure 12, and the syllable �e� is placed on the first note (A) of measure 13, while in Edition 2 and 3 the syllable "e" goes throughout the last two notes of measure 12 and on the first note of measure 13. Therefore, a tie between the two measures is present in Edition 2 and 3 while it is not present in Edition 1.

Alto, measure 35: in Edition 1 the syllable �na� is on the seventh note of the measure (F), while in Edition 2 and 3 it is on the fifth (E).

Domine Jesu

Alto, measure 43: in Edition 1 and 2 the second and the third note (A and G) are semiquavers, while they are quavers in edition 3. The first note (B flat) is therefore a dotted crotchet in Edition 1 and 2, and a crotchet in Edition 3.
