Choralia provides two editions of training aids for Stabat Mater by G.B. Pergolesi, so as to best match the score edition used by the choir. Edition 1 is based on a version published at the Werner Icking Music Archive (edition by Sergio Godínez), while edition 2 is based on a version published by Breitkopf & Härtel (V.A. 60) and available at IMSLP. Some minor differences exist between these two editions, especially on the first movement ("Stabat Mater") and on the last one ("Quando corpus morietur").
