Choralia provides two editions of training aids for the Requiem KV626 by W.A. Mozart, so as to best match the score edition used by the choir. Both the editions are derived from the public domain edition #303-315 available at CPDL. Then Edition 1 is checked against the edition published by Peters (Nr. 76), while Edition 2 is checked against the edition published by Bärenreiter (BA 4538). The vocal parts of the two 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 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 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 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 it is on the fifth (E).


Kyrie

Soprano, measure 11: in Edition 1 the syllable “i” is on the third note of the measure (C sharp), while in Edition 2 it is on the second (D).

Alto, measure 37: in Edition 1 the syllable “i” is on the last note of the measure (G), while in Edition 2 it is on the last-but-one (A).

Alto, measure 40 - 41: in Edition 1 a single sound “lei” is placed on the last note of measure 40, that is tied to the first note of measure 41, while in edition 2 the same sound is divided in a syllable "le", placed on the last note of measure 40, and a syllable "i" placed on the first note of measure 41. In Edition 2 a tie is also shown between the two notes, and its meaning may be debatable.
