Choralia provides two editions of training aids for Psalm 23 D706 by F. Schubert, so as to best match the score edition used by the choir. Edition 1 is based on a version published by Breitkopf & Härtel, reprinted by Kalmus (no. 1066), and available at IMSLP, while edition 2 is based on a version published by Cwmni Cyhoeddi Gwynn (no. 2059). The following differences exist between the choral parts of the two editions:

Soprano I, bar 61 (text "Oe-le"): the last two notes (both Eb) are crotchets in edition 1, a dotted crotchet and a quaver in edition 2. The Schubert's autograph manuscript is consistent with edition 2.

Alto I, bar 20 and 63 (text "stil-len" in bar 20, "vol-le" in bar 63): the second note is E(b) in edition 1, A(b) in edition 2. The Schubert's autograph manuscript is consistent with edition 1.

Alto I, bar 64 (text "mir"): the last note is G in edition 1, B(b) in edition 2. The Schubert's autograph manuscript is consistent with edition 1.
