I've initiated a new blog where I'm going to publish daily Gregorian Vespers. The address is
scriptogr.am/antiphonalejh. The antiphons are transscribed directly from the manuscripts. Most of the manuscripts I've used are available online in which case I've added a link to the corresponding jpg. I've also added St Gall neumes above the square notes. The psalms are completely pointed and the first verse is fully written out like in the Graduale Simplex. I've also included remarks giving the reasons why I chose the particular antiphons. The blog starts on Tuesday, Oct 15. It currently contains the Vespers from Oct 15 through October 21. My plan is, to add the chants for another week every Monday morning.
