A section regarding the Genevan Psalter from PROTESTANT WORSHIP MUSIC by Charles L. Etherington, 1962, pages 97-103.
Though the author obviously has no sympathy with the tradition which produced the Genevan Psalter, this section contains so much useful information that I have taken the liberty to post it. (HRW claims it no longer holds the copyright to this book, but I have not been able to contact the current copyright holders. If you have leads regarding the current copyright status, please let me know and I will take appropriate steps.)
