Organ accompaniment for polyphonic works? Cristobal De Morales' 5-voice Requiem

    I'm sorry if this general topic has been covered and I missed it when searching.

    Our choir is performing the 5-voice Requiem by Cristobal De Morales. I've heard several recordings of the work. On one, by Musica Ficta, the organ accompanies the choir.

    Was this a practice common in Morales' time? Any and all information on the use of organ to accompany polyphony would be greatly appreciated.

    Thank you.

    For Venice there is evidence to colla parte playing of instruments, but Michael O'Connor mentioned here that elsewhere the practice is uncertain.
  • The organist likely played with the choir a whole lot more than we think. However, the organ was prohibited from playing during the Requiem Mass in the 16th century. That does not mean, however, that it wasn't done.

    Franz Xaver Haberl in the Foreword to volume 22 of his complete Palestrina edition (which is on IMSLP) says, that according to Baini in Florence a womens monastery sang double chorus masses by Palestrina and similar works with the not available voices replaced by instruments.

    EDIT: I recently read in Peter Wagner's Geschichte der Messe (History of the Mass), that there is evidence even for completely instrumental masses. Thus a performance of a mass with assisting instruments is in no way problematic. Somewhere I read once, that the first editions of Palestrinas masses with continuo were highly welcomed by the musicians of its time; they even said his art had acquired new splendour.
