Hello, On this website http://www.globalchant.org/about.php You can search for plainchants. Does anyone know what the number after 'hy' means? For example, if you search for Aeterna caeli gloria, you get:
hy 4, am 72 ar 168 hy 1, am 72 hy 3, st 214 etc.
The am, ar, and st are page numbers for different sources where the chant can be found. These are defined on the home page. But what does 'hy 3' or 'hy 1' mean? Is that the mode?
The hy means it is a hymn as the search will usually find the same pattern of notes in Antiphons etc. the number after the hy is the mode. Other abbreviations are listed here, http://www.globalchant.org/about.php
N.B. Please note that this database while very useful is missing more than a few chant manuscripts, e.g. Dominican books.
By the way, the site does say that those numbers refer to mode. If you click on the "magnifying glass" icon for each entry, you'll see a detail page that makes this clear: e.g. http://www.globalchant.org/chant.php?id=350
